This is done by making sure the line width is not less than 1.3 and by modulating its opacity.\nHowever, there is cases where this is not enough. For instance really dense drawings with small lines with little to no curvature still tends to flicker a lot.\nAnother case is when the gpencil strokes intersects the scene geometry. This makes the line less thick to the post process which makes it too small.\n\n## Proposed solution:\nWe propose to implement a Temporal AntiAliasing solution. It is robust and will match Cycles & EEVEE's film filtering if using the same filtering function. This only adds one temporary buffer (low VRAM usage compared to rendering at higher resolution) and is completely self contained (works with transparency and don't interfere with other features).\n\nI propose to only implement this for final rendering since it might introduce flickering that might be annoying while drawing.\n\nHowever this wouldn't solve the issue of gpencil strokes intersecting geometry.\nFor this I propose to erode or reproject the render's depth to match the render sample of the new AA scheme. This should fix the second problem completely.\n\n## Technical details:\n- Implementation just need to be ported from Workbench which has a lighter form of TAA than EEVEE. Also [D10414](D10414) can be of great help to reduce render/convergence time.\n- Depth buffer modification can be implemented after new AA is in.", "EEVEE: Nishita Sky change Sun Rotation causes shader recompilation\nBroken: version: 3.4.0 Alpha\n\nAdjusting Sun Rotation in Nishita Sky texture in EEVEE causes shader recompilation\nwhile adjusting sun elevation is not causing shader compilation and allow to realtime adjustments\n\nThis makes impossible to have animated sun position.\n**Steps to Reproduce**\n- Open .blend file -> switch to viewport rendering\n- Change rotation value with slider\n[#101197.blend](T101197.blend)\n[nitsha.mp4](nitsha.mp4)", "Eevee's AO shades even outside of the distance\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71\n\nBroken: version: 2.90.0\n\nEevee's AO creates certain amount of gradients and shading even outside the Distance area.

I sculpt the mesh in the Solid or Wireframe (I don't sculpt in Wireframe at all, but this problem occurs in that mode as well) viewport and then undo the changes, but the undo does not update the model in the Material Preview or Rendered viewports.\n\nWhy I sculpt this way and why this error (or by design) is problematic and annoying:\n- I can see the topology much better in Solid shading with matcaps. However, I also want to be able to see how the sculpt looks under more finalized lighting settings in real-time while I edit and experiment with different sculpting or placement of facial features, for example.\n- I am constantly undoing brush strokes in a sort of error-correction method of sculpting. Naturally, reducing undoing strokes would be more efficient overall, but not being able to see the reverted mesh from undoing strokes absolutely debillitates confidence of an artist when they're suddenly not working on the most updated model.\n- This can cause bad sculpting errors as one looks from one viewport to the other to \"sanity check\" or simply check progress and be fooled into thinking that the models are synced, when they're actually desynced. The artist might not notice this and continue sculpting, which will update both views again, but it can cause unintentional sculpting errors.\n\nI'm not sure if this was a conscious design choice (2.82 also has this problem. I did not test pre-2.79 versions), but if it was, it makes absolutely no sense why there is even the possibility of anything desyncing between viewports, no matter how the artist works.

[ "GPencil: Brush and stroke size related issues\n**Description**\n\nWhen drawing in grease pencil, control over the brush size and the thickness of the stroke is of course extremely important. Currently, there are some inconsistencies and confusing behavior that need to be addressed. Here is a list of current issues and some new proposals.\n\n - **Brush Radius:** Currently, the brush size can be changed via this slider in draw mode.  The name displays \"Radius\" and the tooltip reads \"Radius of the brush in pixels.\", but this is not consistent with the thickness of the strokes. If the user sets the **radius** to 100px and the *Stroke Thickness* option in the object data properties is set to *Screen Space* the stroke has a **diameter** of 100 pixels. If the *Stroke Thickness* is set to *World Space* the stroke has a **diameter** of 0.1 meters. A simple solution is to change the UI name from \"Radius\" to \"Size\" and clarify in the tooltip that the thickness or diameter of the stroke is meant.\n - **Radial Control:** When the user changes the brush size via the radial control (shortcut {key F}) the control has a **radius** of the given pixel value, not (like mentioned before) a **diameter** of the pixel value set.  \n - **Brush size in World Space** When the *Stroke Thickness* in the object data properties is set to *World Space* the displayed thickness of the strokes in that grease pencil object are calculated via the following formula: `((line_change + stroke_thickness) * pressure * pixel_factor) / 1000.0f` E.g. when all adjustment values are set to their default value then **1px (stroke thickness) = 1mm (world space)**. Currently, there is no way for the user to know this. The UI gives no indication of this and the manual also does not mention it. A possible solution is to change the units of the brush from pixels to meters and also do the right conversion so that the size is correctly displayed in the UI.\n - **Drawing in screen space/world space:** The user can change the stroke thickness (screen space/world space) in the object data properties. That means that *all* strokes in the grease pencil object will be either drawn using the screen space thickness in pixels or the world space thickness in meters. But there is currently not a way to choose the brush size to be in screen or world space. In sculpt mode, the user can choose the brush size \"reference\" (Radius Unit).

This is done by making sure the line width is not less than 1.3 and by modulating its opacity.\nHowever, there is cases where this is not enough. For instance really dense drawings with small lines with little to no curvature still tends to flicker a lot.\nAnother case is when the gpencil strokes intersects the scene geometry. This makes the line less thick to the post process which makes it too small.\n\n## Proposed solution:\nWe propose to implement a Temporal AntiAliasing solution. It is robust and will match Cycles & EEVEE's film filtering if using the same filtering function. This only adds one temporary buffer (low VRAM usage compared to rendering at higher resolution) and is completely self contained (works with transparency and don't interfere with other features).\n\nI propose to only implement this for final rendering since it might introduce flickering that might be annoying while drawing.\n\nHowever this wouldn't solve the issue of gpencil strokes intersecting geometry.\nFor this I propose to erode or reproject the render's depth to match the render sample of the new AA scheme. This should fix the second problem completely.\n\n## Technical details:\n- Implementation just need to be ported from Workbench which has a lighter form of TAA than EEVEE. Also [D10414](D10414) can be of great help to reduce render/convergence time.\n- Depth buffer modification can be implemented after new AA is in.", "Visual bug when using strenght tool in 3D space left for Tool Panel\nOperating system: Windows 10 64Bit\nGraphics card: Nvidia GTX 960M\n\nBroken: 2.80 RC\n\nVisual bug in Sculpt mode, Vertex Paint, Weight paint and Texture paint\n\n1.

When collapsed there is no single type to be shown, creating misinformation. \n\n---------------------------\n\n## Conclusion:\n\nKeyframe colors are important. We propose an improvement by:\n\n - Clarifying keyframe-type colors and shapes in the dopesheet\n - Suggesting this would be useful in the graph editor too ([D5621](D5621))\n - Offer a switch between handle-type shape and keyframe-type shape (instead of the on/off switch for handle-type shape).\n```\n\n```\n*I’m not not a designer, so this is not final or beautiful design just a proposal to visualize my points. \n", "Unify Interpolation In Vertex Paint And Sculpt Mode\nVertex paint squares colors when it interpolates, while the paint tools in sculpt mode do not.

To test the problem and demonstrate it, I built a test project with different scenarios.\n\nInitially, I had noticed that certain color gradients had some sharp contrast. Since it was a B-Spline, I expected something really smooth all the way, but it was not the case.\n\nMy expectation of a B-Spline look was as demonstrated as on the following image shown on the Wikipedia article.\nFile:B-spline_curve.svg\nB-spline\n\nIn Blender, it works well when a control point is perfectly halfway of its left and right control point neighbors. If we move the control point closer to the left or right neighbor, the curve starts to become sharper, which is not the behavior described about the B-Spline. Therefore, the trick to make it appear correctly is to position any control point perfectly in the middle of its neighbors. Varying the value (black to white) does not break anything in the expected behavior.\n\nAs far as I remember, to display a B-Spline of more than 3 control points, we have to reuse the previous control points to create this smoothness. It does not look like that here, but even with 3 control points, the smoothness is not there when moving the second control points towards the first or the third.\n\nI tested the problem in the shader nodes to demonstrate the problem. However, the ColorRamp is available in many places like the Compositing, Geometry Nodes and other places. I presume the problem is in a library common to all places where the color ramp is accessible and probably also any B-Splines functions (maybe animation too).\n\n**Project configuration**\nVisualizing the B-Splines is not direct in Blender. I created a project where there are planes side by side showing the equivalent of the Y value on the X axis based on the texture coordinates.\n\nEach plane is a test and has a different setup. Here are the descriptions of each test objects in the projects.\n\nBSpline_Test_1: Displays correctly. Control point in the middle. Basic.\nBSpline_Test_2: Displays correctly. Control point in the middle with closer control points.\nBSpline_Test_3_Broken: Does not display correctly. Control points in the middle.\nBSpline_Test_4_Broken: Same thing with a larger view. Illustrates the sharp corners.\n\nEase_Test_1, 2, 3: Display the Ease interpolation.\n\nI also included the “Ease interpolation”. I’m not sure if there is a problem related like the B-Spline, but it does not show so smooth results. The test “Ease_Test_1” shows a problem where the tangent is always aligned with the X-axis. Is it normal? I would have expected a smooth curve when inserting a new control point. Unlike the B-Spline the Ease interpolation is always rounded, but new control points inserted between two other control points always create a “plateau” effect. To me, there is also a problem too here with the smoothness when using the Ease interpolation.\n\n**Test results**\nHere’s the result shown in the project here.\n\n\n\n" ]

This works correctly for a single F12 render, and matches the values shown in the render window, but when rendering an animation (Ctrl-F12), the Time Elapsed shown is the *total* elapsed time for all frames so far, not just the elapsed time for that single frame. This isn't really a problem in itself, but this total time is evidently also being used in the Time Remaining calculation, which a result becomes more and more wildly inaccurate with each subsequent frame, presumably because the calculation wrongly assumes that that single frame has needed all the accumulated time to render however far it's got.\n\nFor example, if a single uniform frame took 100s, after 10% of the first frame of an animation it would correctly show **Remaining 01:30.00**, **Elapsed 00:10.00**, as in the render window. But on the 101st frame, after 10% progress it would show **Elapsed 2:46:50.00** (100x100+10 seconds), but **Remaining 25:01:30.00** (10,010x9 seconds), wrongly implying this single frame will take over a day to finish rather than about 90 seconds!\n\nPlease note that this report is *not* about the expected inaccuracy of the estimate early in the progress of a frame, which I realise is unavoidable given the variation in render speed for different tiles within a frame.\n\nI believe a fix for this bug might be to either:\n\n - change the Elapsed time in the Infotip to be the elapsed time for just the current frame (as it already is in the render window header) so the Remaining time will then be calculated correctly; or better still...\n - when rendering an animation, change the Infotip times and the progress bar to show the overall progress of the entire animation (i.e. frames rendered divided by total frames) instead of the individual frame progress (i.e. tiles rendered divided by total tiles). This would give a useful indication of the total (estimated) remaining time to render the full animation.\n\n\n\n\n\n - Open any version of Blender 2.77 or later, with the default startup file or any other scene.\n - Depending on the speed of the test hardware and the complexity of the scene, optionally select Cycles render engine, the CPU device, and/or increase the sample count, so that the F12 render time is at least e.g. 20-30s (this is because very short renders make it difficult to see the problem, as the progress bar jumps straight to e.g. 98%)\n - Now start rendering the scene as an animation using Ctrl-F12 (the default of 250 frames is fine).\n - While rendering, hover the mouse pointer over the Render progress bar in the status bar to show the popup Elapsed/Remaining Infotip (this applies to Windows 10 - I don't know if this is similar in Linux or MacOS)\n # Notice that the time values in the Infotip agree with those in the render window for the first frame, but with each subsequent frame the Elapsed time accumulates and as a result the estimated Time Remaining becomes more and more inaccurate.\n \n\n\nI realise this is not a serious bug, but it has been long standing and is will hopefully be quite easy to fix, so it would be good if this could be included in a future version.\n\nMany thanks, Ross\n[edited to hopefully correct my maths!]\n\n\n", "Curve to Mesh node creates wrong face orientation with cyclic profile curve\nOperating system: Linux-6.1.26-x86_64-with-glibc2.37 64 Bits\nGraphics card: AMD Radeon RX 6800 XT (navi21, LLVM 15.0.7, DRM 3.49, 6.1.26) AMD 4.6 (Core Profile) Mesa 23.0.3\n\nBroken: version: 3.5.1, branch: Unknown, commit date: Unknown Unknown, hash: `Unknown`\nWorked:\n\nThe `Curve to Mesh` geometry node creates incorrect face orientation when using a cyclic `Profile Curve`.

Only by the use input sockets can our users tweak the usage of the node group. As those input sockets can only connect to other input sockets the freedom of tweaking is limited.\n\n**Proposed situation**\nIn the proposed situation I want to have an option where the users can ‘expose’ attributes of a node to the nodegroup level. My proposal will be similar to “Insert key-frames” in workflow.\n\nExample:\n\nWhen the user wants the Filter type of the Blur node to be exposed, the user can open the attribute menu and will be ample to select “Expose to node group”.\n\n\nNote: this menu needs will hold a new operation when in the editing a node group: “Expose to group” and “Dispose from group”. We can also add a key to these operations (“E” is not assigned yet in node editor when hovering over a node attribute as far as I can see.)\n\nWhen the node group is closed all exposed attributes will be rendered in the node group.\nBy this the user will still be able to tweak this setting and make changes per instance of the same node group.\n\n**Open issues**\nIt should also be clear to users which attributes are exposed. We can use a Color, but it won’t be clear when an attribute is keyframed and exposed. We could also solve this by having a gradient or checker fill for color, or something else.\n\n**Technical stuff**\nStore references of exposed Node/RNA attributes in the nodegroup.\n\nThe main usages of node systems are cycles and compositor. Both of them flatten the node tree so all instance specific settings can be handled during the flattening process. For texture nodes we can use a reference to the nodegroup instance when executing (haven’t looked into the current state of the code yet). \n\nChanges to addons needs to be done by the addon developers themselve. There might be a breakage or at least new blender feature that needs to be supported. \n\nAs the current node system is not changed in Blender2.8 I think it is very plausible to implement this in 2.79 and merge it in Blender 2.8 when finished.\n\n\n\n", "isolate collection doesn't work on nested collections.\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 536.99\n\nBroken: version: 4.0.0 Alpha\n\nisolate collection doesn't work on nested collections.\n\n\nSee attached video.

Changing the radius to have a higher value makes the ring go away. Setting the value to near zero values such as 0.002 will still have the ring, but smaller. Both distributions GGX and Multiscatter GGX have the problem. Only the lights with a radius parameter have the ring (point and spot lights). Area lights use a size parameter and behave differently, so they do not have this issue.

I have an environment with foliage billboards that appear like they are slightly head-locked and they sway around a lot when moving in VR. I later realised I could reproduce similar artifacts outside of VR and then realised that disabling denoising avoided the artifacts in the editor and in VR.\n\nIt seems that Eevee's denoising introduces some kind of latency related to how the alpha blending is handled which results in temporal, visual artifacts while the viewport's perspective is changing.\n\nI'd say the reproduction below probably doesn't represent how significant the artifacts feel in VR but I think it highlights the same underlying issue (the same two workarounds that affect the editor, also help in VR).\n\nTurn on Viewport Shading: Material Preview or Rendered\n\nDelete cube\nAdd plane\nAdd material (default principled BSDF is fine, though in my case I'm working with emissive shaders and I have a modified build of Blender supporting equirectangular image textures that let me access their alpha channel)\nSet material Base Color to an Image Texture.\nCreate a new image and generate a Color Grid to set as the base color.

That's quite different to the original artifacts I saw in VR for my use case but still it seems to represent the same underlying issue.)\n\nUnder render properties, toggle Viewport Denoising and perform the same viewport movements to compare.\nWith Viewport Denoising back on, switch to using Alpha Clip instead of Alpha Blend and again compare.\n\n[eevee-denoise-artifacts.blend](eevee-denoise-artifacts.blend)", "Artifact with cycles (interaction with moving spotlight and motion blur)\nOperating system: Windows-10-10.0.19045-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1050 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 516.94\n\nBroken: version: 3.4.1\n\nI wouldnt describe it as a error, more as a artifact in cycles, basically when you parent a light to an object with motion blur, it doesnt behave as expected, it clips into objects and deforms due to the motion blur, there is no easy way to explain this, its better to show it, keep in mind that the spot light in these examples is completely Static! its just parented to the empty that also is parented to the camera, what is moving is the empty, light in real life doesn't behave this way!\n\ni first noticed this in a render i did for my animation \nrender: view\nproject file: view?usp=sharing\n\nso i did a test render and the problem pressists\nrender: view?usp=sharing\nproject file: view?usp=sharing\n\n\n\nAll the best!

Why there is an element of chance I cannot work out.\n\nTry moving the playhead around between markers (which indicate a camera bind in the strip's scene) and notice how the bind almost always fails to apply.\n\nNow try jumping from region to region and notice how the camera bind is almost always 1 step behind, so it is never applied, place the playhead within the current region and it updates without fail.", "Geometry Nodes: Disabled from viewport object is not visible as instance\nOperating system: win10\nGraphics card: 1050ti\n\nBroken: Current main.\nWorked: Never.\n\nDisabled from viewport object is not visible as instance.\n\nOpen attached file and check/uncheck `As Instance` option of _Object Info_ node.\n\n", "Generic Rigid Body Constraint Bug\nOperating system: Windows 10\nGraphics card: Radeon RX 470\n\nBroken: 2.83.0\nWorked: Unknown if it ever worked\n\nAngle limit not only doesn't work but causes weird neverending twitching back and forth\nUPDATE:\nTwitching happens for both cases when both rigid bodies are active and when one of them is passive.\n[M0DJ38oWQo.mp4](M0DJ38oWQo.mp4)\n\n1.

But this leads to using `Invert` on the mask potentially hundreds of times per day.\n\n### Syncing Selections across Modes\n\nFor the implementation of Paint Mode it will be very beneficial to start syncing selections between various modes. \nSo if a selection is made in Edit Mode it will also appear as masked in Sculpt/Paint Mode (This would likely be a direct conversion every time you switch modes)\nThis will be less confusing and disconnected if both the selection in Edit Mode and the mask in Sculpt/Paint Mode are areas you CAN affect.\n\n### Masks vs Selections\n\nA current plan for the implementation of Paint Mode and the new Curves object type is to use \"Selections\". \nThe use case for sculpt mode masks and selections is essentially the same: \n**You define a temporary area that should be affected by your operations.**\n\nThe issue is that \"Masks\" also refer to the concept of for example creating an attribute (like a vertex group or color attribute)\n or a grayscale image texture and using it as a factor for shader/geometry nodes. The use case here is quite different:\n**You save an area for repeated use in materials and procedural networks.**\nFor example layering textures.\n\nReplacing the current concept of sculpt mode masks with selections would avoid confusion and make the use case of selections and masks very clear.\n\n# Proposal\n\n### Selection instead of Masking\n\nWe need to test the following behavior:\n- Rename \"Mask\" to \"Selection\" or \"Selection Mask\"\n- Unselected areas are darkened with an overlay\n- Selected areas are affected by brushes & other operations\n\nThere are use cases that are important to keep in mind with this change:\n- When entering sculpt mode, everything should already be selected.\n- Previous workflows (Mask brush) to create a deselected area and should still be accessible.\n\nOther areas of Blender will still refer to \"Masks\" like a Texture Mask in the brush settings, mask nodes, grease pencil layer masks and motion tracking masks.\n\n### Offer a preference to use the old behavior\n\nThere should be an option in the preferences to invert the selection behavior globally in sculpt/paint mode and get the old behavior back.\nTo what extend the inverted behavior would be done needs to be tested.", "Inconsistent pressure behavior between the size and the strength in the sculpt mode\nOperating system: Win 11, Wacom Intuos Pro\n\nBroken: c1beaea80f97\n\n\n\nThis bug report was requested by @JulienKaspar.t.\n\nThe strength pressure feels totally flat once the size pressure is disabled.

But it relies quite a bit on the asset and the scene it’s being dragged into (e.g. the size relative to the destination scene, the exact normal of the snapped to surface), etc. Users may want to adjust the rotation, the scale, the up-axis, use the origin for snapping rather than the bound-box (e.g. to place trees so they are partially covered by the ground plane), etc.\n\n### Basic Design Idea\n\nRather than setting these options before dragging (where you don’t get visual feedback) or while dragging (where it’s awkward to give input because you’re holding a mouse button), the Operate->Settings paradigm of Blender should be used: First the object/collection is dragged in and placed using basic snapping, then we provide a visual way to keep adjusting the transforms and parameters until the user is happy with the result.\n\nHowever, this placement method isn't just useful for dragging in assets. It is useful as a general transform tool and should be created as such. So this is a proposal for a general placement tool with bounding-box or origin based surface snapping, that gives access to most important transforms and properties for placing an object. In some way or another, it could be (temporarily and optionally?) activated after dragging an object or collection asset into the scene. If more advanced transforms are needed, the user can still access the proper transform tools & operators.\n\n### Temporary Activation\n\nHaving to activate a placement tool every time an asset is dragged in can be annoying. Blender could automatically activate it, at least in some temporary fashion. For example, the tool could temporarily override the active tool after dragging in an asset. Deselecting the dragged in object would bring back the real active tool. If the user wishes to go back to the placement tool, that can be explicitly enabled again in the toolbar.\n\n### Tool Design\n\nTODO", "Empty Hair object in sculpt mode, set select mode control points has wrong tooltip, doesn't show hotkey, adds new hotkey to wrong section\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.15\n\nBroken: version: 3.4.0 Alpha\n\n\nThe new empty hair object has in sculpt mode two selection methods.

My preferences are set to use both the CPU (AMD Threadripper 32) and the GPU (geforce 4090) in OptiX (or CUDA, doesnt seem to matter). Once the file opens, material preview works fine. (refer to \"materialpreview.png\") but when i click render preview (refer to renderprevier.png) all i see is my rig. Anything with a texture is a similar dark grey as the default blender background. I can move the camera around fine, but no textures are visible. If i click material preview again to switch back, blender freezes and must \"end task\" in task manager. If i turn off the GPU assistance and only have the CPU enabled, everything works as it should. \n\nYesterday i updated to latest windows 11 update. I also updated my gameready drivers for my 4090. When the issue started, i thought it might have something to do with gameready drivers so switched to Studio drivers. This did not fix it. \nAssuming that these updates may have broken my file, i rolled back windows 11 drivers to most recent previous version, and did the same with the nvidia studio drivers (uninstalled 5.35.... installed 5.31).

A unit of work is a single tile (the same size as the frame buffer) with a varying number of samples to render for each scheduled task. \n\nTwo accumulation threads, one for the CPU and one for the GPU, run almost independently until the sum of samples has reached the number of required samples (the threads have to synchronize on the number of rendered samples and the offset for random number generation). \n\nOn every execution, each processor renders the amount of sample that is most suited to its capabilities. The initial number of samples assigned for the GPU is higher than the one assigned to the CPU. As mor rendering information becomes available, the number of samples per device is determined based on the number of samples it can process within an update interval. Only GPU thread updates the display while the rendering is still in process. It allows for more flexibility to determine the launch frequency/number of samples on the CPU device. When all samples are rendered, the two buffers are merged, to produce the final output (the overhead of this method). \n\n```\n\n```\n\nThis is a preliminary and quick implementation, without software design consideration, as a proof of concept to show the benefit of distributing work on two processors with significant capability differences.

This only works well for mesh and grease pencil edit-mode, however it has some down-sides.\n\n- We would be using all number keys by default, any additional modes or sub-modes wont fit.\n- Some sub-modes wont fit:\n - Particle edit (currently uses keys 1-3 to switch sub-modes).\n - Weight paint.\n - Texture/Vertex paint.\n\nThe ideal solution in this case isn't clear, either we accept loosing shortcuts for switching sub-modes or accept some inconsistency (having to add a different shortcut for sub-mode switching for modes besides edit-mode).\n\nThere are plans to merge painting modes into a single attribute painting mode, even if this is done, it might make sense to expose weight/texture/sculpt as sub-modes... either way, I don't think we should rely on this change unless it's committed to master before the keymap changes. The same applies to the future of Particle Edit once the new Hair object type is implemented.\n\n**What to do when pressing a modes key a second time?**\n\nCurrently nothing is planned. Options are to toggle the mode or cycle through sub-modes. Both have their pro's and con's so there are no plans to use second-time presses.\n\n**Is overwriting edit-mesh modes acceptable?**\n\nBy switching directly into vert/face/edge modes, this will overwrite the mixed modes which the user will need to manually set every time they enter edit-mode.

Animated strip properties would only be evaluated and flushed on frame change or when the whole frame needs refreshed.

However, there are many situations where it would be handy to be able to edit actions that can be reused on other levels instead (for example, actions for different sets of colour+intensity cycles for lamps - e.g. for a disco scene or something like that).\n\n**Problem**\n*1) How do we make it clear to users which level/slot they're editing?*\n- For example, with a single Cube selected, we could potentially have Scene, Compositing Nodes, World, Cube Object, Cube's Material 1, Material 1's Texture..., Material 2, ..., Cube Mesh, ShapeKeys, Particle System 1, Particle System 2,..., and perhaps a few others I've overlooked.\n\n*2) How do we allow users to select which level + slot they're editing?*\n- This naturally follows from the first problem. Basically, if we can display a slot, we can probably try to reuse that mechanism for primitive selection techniques.\n\n**Solutions**\n # **Level + Slot Selectors** - This would be similar to what the IPO Editor used to have (File:ManAnimationEditorsIpoWindowDefaultViz.png).\n - *Benefit:* This is a fairly self-contained approach, and one of the easier ones to implement.\n - *Problem 1:* This was quite nasty if you selected another object that didn't have the types of data that the previous one had. Then again, the Properties Editor suffers from similar problems too.\n - *Problem 2:* Also, it didn't really handle things like materials that well (these were accessed using a number box to choose the index being edited)\n # **Mini-Outliner of Available Slots** - This is a more advanced version of the Level + Slots idea, except that we display a mini tree of available levels that can be edited given the current selection, with the hierarchical relationships between datablocks visible\n - *Benefit:* This copes better with things like Materials and Particles\n - *Benefit:* This is still a \"self-contained\" approach (i.e. each editor doesn't need to know anything about other editors' states)\n - *Problem:* We'd have to develop a new widget to do this - somewhat hairy in the current UI widget toolkit, but we'd want to do this for RNA Path building anyway\n - *Problem:* We'd end up with a semi-blocking/overlapping view that users have to interact with everytime they hunt for this info.\n # **Defer to Outliner (Proper)** - Instead of creating our own outliner tree and using a localised pointer, we just defer these capabilities to the main Outliner. Thus, clicking on Action Slots there (or just the Animation Data entries) tells the Action Editor where it needs to be.\n - *Benefit:* Potentially simpler for users who just expect applications to be monolithic blobs where every single view cooperates with every other view to present a single editing state/context\n - *Problem:* What happens when we've got multiple of each type of window, and we want to have separate views in each?\n # **Controlled by DopeSheet** (From an old suggestion by @venomgfx) The Action Editor can only be entered via DopeSheet. Double-clicking on a channel there opens Action Editor for just that action+level (i.e. in effect it filters the visible channels to just those in that action). When selected object changes or we exit action editor (i.e. back to dopesheet), the slot/level pointer stuff gets reset and/or the Action Editor simply becomes unavailable.\n ", "Linked Instances Across Scenes have unreliable updates when editing their common mesh data.\n\nBroken: 2.93.4 LTS;\nBroken: master\n\nWith two different objects in two different scenes sharing a same obdata Mesh, editing the mesh in one of the scene can fail to properly update object in the other scene.\n\n- Open attached file.\n- Go to scene 2.\n- Switch to Edit mode.\n- Assign the red material (first slot) to the cube in edit mode.\n- Switch back to Object mode.\n- Go to Scene 1, the Cube in Scene one still uses the second slot material (green).\n# Switch to edit mode and back, now the cube is shown with expected first material slot (red) as well.\n\nNOTE: If you replace step 4 by a mesh geometry editing (e.g. rotate the mesh in Edit mode), in current master there is the same missing update issue in Scene 1, but in 2.93LTS it is properly updated...

Pressing undo once will only remove the last Grab brushstroke as expected but also revert the active brush to the Draw brush which is not expected.\n\nAfter loading factory settings, the problem doesn't exist.

This core functionality existed as late as 3.3.1 in the former Pose Library system under the option \"Replace Existing\". However, there is currently **NO** way to overwrite an existing pose asset at ANY time without **FIRST** assigning the pose you want to change and **THEN** changing the bone positions. This is **extremely restrictive** and prohibits the user from updating key poses at will.\n\n**Real world example** : While modeling a chair prop for a character, I posed the character in a seated position, and created a pose asset. As the chair design changed over time, I re-posed the character to accommodate the new design. However, because the \"Seated\" pose asset was not the currently active action, there was **NO** way to overwrite the original pose with my new work. Assigning the original \"Seated\" pose asset in the Action Editor caused any new pose I just made to be lost. This is why I consider this a significant regression, because a user can no longer update a pose at any time they desire.\n\nUnless the new Pose Library is given the basic functionality to overwrite an existing pose with a single click, the old Pose Library system should remain active in Blender.\n\n**I would go further to say that both systems should actually co-exist** , since they are both good and actually complement each other. The new system is better for visual feedback as it provides thumbnail images for each pose, and the old system is better for sheer speed and flexibility (especially during weight painting) since only a single click is needed to overwrite a pose, you can immediately RENAME a pose (without needing to have a separate Asset Browser window open), no actions have to be assigned for it to work, and no thumbnails clutter the interface.\n\n1. Open attached example .blend file. Ensure Pose Mode is active.\n2. Observe the \"Lean Back\" pose asset is currently active in the Action Editor on the left.\n3. Adjust the pose as desired.\n4. Attempt to overwrite the \"Happy\" pose with your current work.\n5. Note that Step 4 is no longer possible in Blender 3.5.1, you will lose your current work if you assign the \"Happy\" pose in the Action Editor.\n\n**To workaround this severe limitation you must perform 3 additional steps**\n6. First click \"Create a New Pose Asset\" for your modified pose in the Action Editor.\n7. Next, (in a separate Asset Browser window) delete the original \"Happy\" pose by right-clicking it and choosing \"Clear Asset\" \n8. Finally, rename the new pose asset to \"Happy\".\n(As you can see, the regression of the missing \"Replace Existing\" feature in Blender 3.5.1 results in many unnecessary steps compared to the ultra-concise workflow of Blender 3.3.1).\n\nThank you so much for your time and for looking into this issue.\n\nSincerely,\nAdam Janz\n\n", "Bone's Transformation constraint numbers won't be symmetrized correctly.\nOperating system:Windows 10\nGraphics card:RTX 2070\n\nBroken: 3.3.1\n\n[Use this file](https://projects.blender.orgattachment)\n\nThis will break:\n\n- open the blend file\n- delete the selected Left bone\n- select Right bone and symmetrize it\n- check both Right and Left bones' Transformation constraint setting.

The vertices created by the by the bisection are mapped to the original mesh data in a way that appears to be based on blenders internal representation of the mesh and not based on something observable to the user.\nThe behavior when selecting should feel consistent to the user. To fix this, I suggest that the vertices created by the bisection should always map to the vertices on the original mesh that are on the removed side of the bisection plane. This way users would be able to tweak the centerline of the mirrored mesh in while using \"On Cage.\" As it is currently implemented, there are vertices that affect the mesh that cannot be accessed through normal click selection unless \"On Cage\" is off.\n\n**Example**\n\n\nSelect the +X or -X face of the default cube and scale it by 0.5.\nAdd the mirror modifier and select bisect for the X axis so that the object is mirrored and bisected about the X axis.\nTurn on \"On cage\" for the mirror modifier then enter edit mode for the object.\nWhen selecting the vertices on plane X=0, you should notice that two of the vertices correspond to visible mirrored vertices and two correspond to vertices removed by the modifier. \n\nSimple scene showing the behavior. \n[MirrorSelectOnCagePapercut.blend](MirrorSelectOnCagePapercut.blend)\n", "Boolean Modifier is evaluated if an object linked to the cutter object is link-duplicated\nOperating system: Linux-5.4.0-58-generic-x86_64-with-debian-bullseye-sid 64 Bits\nGraphics card: GeForce RTX 3070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 455.38\n\nBroken: version: 2.91.0\n\n\nSuppose ObjectA has a boolean modifier, the target object of which is CutterA.

One of the issue with this is that it kind of conflicts with the same functionality on macOS which has system-wide option for the same functionality.\n\nThe idea to mitigate this confusion could be to introduce \"Auto\" display configuration. which will leave the final display transform to the OS.\n\nThere are some open topics with this proposal:\n\n- What should be the way of checking how render result would look like on a non-HDR screen: is it something to be done via the system-wide settings in the OS, or is it something to be done by adding/ensuring clamping the sRGB display OCIO configuration (possibly presented as a different display from the current sRGB)?\n\n- How to apply the \"Auto\" display transform on the saved images? Auto could be a boolean too.\n\n- Look at virtual displays as potential solution: 1082\n\n- Should Extended sRGB be its own colorspace, or a boolean toggle?\n\n### DCI-P3 display configuration\n\nThe title is kind of self-explanatory: there needs to be a configuration for the displays which use DCI-P3 color space.\n\nOne of the challenges is to preserve the Filmic View, which is currently designed for the sRGB screens. Arguably, it should be a look as it is often used for an artistic reasons. Nevertheless, this is a topic of investigation for the P3 display configuration.\n\n### ACES support\n\nACES is what a lot of studios and hardware manufactures are aligning up, and this configuration seems to be useful to have regardless of HDR story.\n\nAn argument for the ACES in the context of HDR is that it seems that it simplifies color grading process, ensuring that the final frame will look as close as possible to what artists had in mind as when viewed on various projectors and displays.\n\n## Draw manager & UI\n\nThere are following points which seems important for the decision making:\n\n- On macOS it seems to be very easy to provide window content in a specific color space (which is communicated to the NSWindow), and leave the display transform to the OS.\n- Blender needs to become usable on XYZ projects.\n\nThis leads to the following proposal: the entire Blender UI needs to become covered by color management of some sort. Possibly, render the whole Blender UI in wide enough color space (rec2020?). The final display color space transform is then either done by the OS, or as a window-wide shader.\n\n## Image IO\n\nFor images it is already possible to override display transform. So technically it is possible to apply proper tone mapping to make non-HDR image format look good.\n\nA possible life quality improvement could be to somehow streamline preview of the saved images. Currently it is kind of invisible, and the only way to know the final look is to open the file.\n\n## Video IO\n\nBlender uses FFmpeg, which seems to supports HDR. However, in Blender the integration is historically hard-coded to be 8 bit per channel.\n\nBoth FFmpeg reader and writer needs to ensure to support higher bit depths.\n\nFrom implementation details for the writer the interesting functions are `BKE_ffmpeg_append` and `BKE_ffmpeg_start` from `writeffmpeg.c` (this trickles up to the `bMovieHandle` abstraction used by the render pipeline). The frame API needs to be changed to accept `ImBuf` instead of `int*`, and the `IMB_colormanagement_imbuf_for_write` needs to be checked from a point of view that it does not enforces clamp.\n\n", "Blender Interface Does Not Respect Windows Colour Profiles\nOperating system: Windows 10 Home 1909\nGraphics card: Nvidia GTX 1080\n\nBroken: 2.83.0 on Windows\nWorked: 2.83.0 on OSX\n\nBlender's interface shows incorrect colours on high colour gamut monitors in Windows 10.

[ "Mirror Modifier On Cage Selection Papercut \nBroken: 2.93.4\nWorked: Maybe never.\n\nWhen in edit mode, using the \"On Cage\" option for the mirror modifier results in some unintuitive behavior when selecting vertices created by the bisect feature. The vertices created by the by the bisection are mapped to the original mesh data in a way that appears to be based on blenders internal representation of the mesh and not based on something observable to the user.\nThe behavior when selecting should feel consistent to the user. To fix this, I suggest that the vertices created by the bisection should always map to the vertices on the original mesh that are on the removed side of the bisection plane. This way users would be able to tweak the centerline of the mirrored mesh in while using \"On Cage.\" As it is currently implemented, there are vertices that affect the mesh that cannot be accessed through normal click selection unless \"On Cage\" is off.\n\n**Example**\n\n\nSelect the +X or -X face of the default cube and scale it by 0.5.\nAdd the mirror modifier and select bisect for the X axis so that the object is mirrored and bisected about the X axis.\nTurn on \"On cage\" for the mirror modifier then enter edit mode for the object.\nWhen selecting the vertices on plane X=0, you should notice that two of the vertices correspond to visible mirrored vertices and two correspond to vertices removed by the modifier. \n\nSimple scene showing the behavior. \n[MirrorSelectOnCagePapercut.blend](MirrorSelectOnCagePapercut.blend)\n", "Viewport Z-Bias & retopology overlay related issues\nSince this is being reported frequently and retopology overly has caused some weird issue with mask display as well previously, it's best we keep track of them in a central place so we could check if any particular fix is working for all situations:\n\n------\n\nProblem still presents:\n\n- Retopology overlay affecting other parts of the drawing/picking operation: #109115 #107768 ~~#109277~~ ~~#107411~~\n- (Potentially related) Selecting when X-Ray turned on is not visually effective and then switching to face mode crashes: #110136\n\n------\n\nFixed:\n\n- ~~Wireframe visible in close distances: #110048 #109040 #109514 #109499 #109685~~\n- ~~Retopology overlay 0 z offset problem: #109662~~\n\n-------\n\nProbable cause:\n\nAs suggested in 107768#issuecomment-937545 , I believe the problem here is that\n\n1. `DRW_object_is_in_edit_mode` does not exclusively check if object is in edit mode, but it combines other logics that affects drawing and stuff.\n2. `XRAY_ENABLED` marco is not always accompanied with `RETOPOLOGY_ENABLED`, this leads to inconsistencies in the user interaction and the display.", "GPencil: Missing functionality in Vertex Paint mode Selection tool (left-click-select)\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1050 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 511.65\n\nBroken: version: 3.6.0 Beta\n\nWhen Points select is enabled in Vertex Paint mode, the Selection tool doesn’t behave like in Edit mode:\n- it cannot select a single vertex,\n- a left click away from points doesn’t deselect them.\n\nAdditionally there is no color picker when this tool is selected, so if you select some points to use the Set Color Attribute operator on them, you can’t see the current color or choose a different color, unless you switch to a different tool.\n\nMake sure you use Left Click Select in Preferences > Keymap\nAs shown in video, open any stroke in Vertex Paint mode, enable Points select and select the Selection tool.\n- You can box select points but can’t left click on a point to select it and you can’t click away to deselect points.\n- There is no color picker.\n<video src=\"attachment\" title=\"Selection Bug-1.mp4\" controls></video>\n\n", "Mesh modeling performance regressions\nList of performance issues that we would like to fix or investigate for 2.80:\n\n* Transforming vertices in edit mode on high poly meshes is slow, due to overhead of depsgraph, mesh updates and and batch creation.

They are not related to geometry, and not related to illumination, since even the light AO regions appear noisy. Disabling adaptive sampling or changing the threshold to extremely small values removes the issue. Values for the noise threshold look inadequate in these regions. Setting it to 0.01 gives around 27 out of possible 256 light difference between adjacent pixels in HSL color. In regions with reduced noise, the level looks similar to what it should be, you can see both on the image below. The noise disappears when threshold is turned off, so it's not related to maximum samples count. Same issue does not appear on baking direct or indirect light and the noise level seems adequate. It's not related to denoiser, since it's not working in baked maps (unfortunately).\n\nIt's hard to imagine synthetic scene in which the situation will repeat itself. In the attached scene, you just need to click the bake button and see the results. Try changing the Noise Threshold values or disabling it.

Because its weights aren't correctly interpolated, it instead ends up with a bunch of spikes at each of its original vertices.\n\nThe middle sphere has vertices weighted in a gradient from 0.00 to 0.50. It serves as an example of a feasible real-world application which would be broken by this kind of behaviour. Perhaps the original vertex weights act as a sort of base heightmap for a terrain model, and the changes made by the Subdivision and textured VertexWeightMix modifiers add an extra layer of detail. In this case, the clear and useful behaviour would be for behaviour to be continuous in the transition from 0.01 to 0.00.

But in typical painting workflows you'd expect to have this be a more universal toggle that affects all tools!\nToggling this per brush is not a reasonable solution.\n\nThere are multiple approaches to fix this.\n\n## Proposal: Alpha Auto-Masking\n\nThere is already a design in place for sculpt and paint mode. There we use auto-masking to easily target specific areas as a mode setting.\nThese are meant to be instantly accessible with a pie menu on `Alt + A` and would affect all tools and brushes.\nThis would likely be the most intuitive and fastest option.\n\n## Image Editor Inclusion\n\nIf we decide to replace the brush option with an auto-masking option this puts further pressure on implementing the same options for the image editor.\nThis might be reason enough to lower the priority for now, until the image editor can be properly prioritised to mirror the 3D viewport paint mode features.\n\n## Long Term Alternative\n\nOther image painting applications such as Krita implemented this as a toggle for any individual layer to paint on.\nWhile this is not likely to implement this way right now, it could be kept in mind for the UI of the [layered textures design]().", "Reload Image (in Image Texture Node) not worked with Cycles selected. bpy.ops.image.reload()\nOperating system: Windows-10-10.0.19045-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 4080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 531.61\n\nBroken: version: 3.5.1\nAlso not working in 3.6 beta\n\nReload Image (in Image Texture Node) not worked with Cycles. bpy.ops.image.reload()\nIf Cycles selected as active render - it's not working, but if set to Workbench or Eevee - all works fine.\n\n1.

[ "Brushes Storage\nIn Blender, one of the core issues with brushes, is that they are currently stored *inside* the blend file. This is not very useful, because it puts a large burden on users to then manually save and load brushes for each project or blend file. \n\nInstead, we would like for brushes to be stored centrally, so that they will be accessible from any blend file on the user's system.\n\nHere's how this could work:\n\n - Brushes are stored in a central location, much like LookDev HDRIs\n - Adding or removing a brush will affect this central repository\n - Any local changes to a brush is not saved unless users explicitly choose to do so, otherwise any temporary change would overwrite the main brush in the repo\n - Brushes are stored as 1 brush per blend file, so it's easy to manage them and share them, but will be cached in an index for fast loading and browsing. \n\nNote: For brushes to be more useful and work well, we will also need to;\n - Create automatic dynamic previews of the brush, so you can see the opacity, spacing, texture, falloff, and so on. Otherwise browsing brushes will largely be a guessing game\n - Have a way to see brushes for all tools, and let selecting the brush set the tool\n - Have some way for users to categorize brushes (the primitive method would be to use file system folders - a nicer way could be via the asset browser)\n\nOpen Questions:\n - Should brushes tie into the assets system somehow, and should you be able to manage them in the asset browser?" ]

In the modal operator equivalent (Shortcut C) it's just about pressing + and - or using the scrollwheel but this is not an option for the Tool. Generally there are no shortcuts for Tools before they are initiated. If the settings need to be changed then this needs to happen in the Tool Settings in the header or sidebar.\nBut changing the radius via that slider in the settings is awkward and appears visually glitchy since it's intersecting with the UI itself.\n\n\n\n## Proposals\n\nSo how can this be fixed. Ideally the solution should be as straight forward as possible without reshuffling the keymap. But it is very important that this is a general solution that can also be used for other brush-like Tools in the future (like proposed retopology tools that also rely on a brush radius)\n\n**1. More integrated modal shortcuts**\n\nOnce a Tool is initiated (usually by click & dragging) it uses the modal operator. This means that when using the Circle Select Tool and click & dragging, the radius can be changed with the mouse wheel & the + and - keys. \nThe current issue with this is that the Gizmo drawing is conflicting with the Tool Radius and that any changes to the radius are not updated in the tool settings.\nKeeping these 2 more in sync would be one solution or at least a great added feature.\n\n\n\nIt should be updated to the way the annotate eraser tool works but with more accessible shortcuts for radius changes if the mouse wheel is not an option (pen users)\n\n**2. Include Brush Tools in more modes**\n\nAnother solution is to redesign the Circle Select Tool (and any tools, present or future, that work similarly) as a brush like in sculpt mode or the painting modes.\nThis means that when the Tool is active it does have a set of shortcuts that can change the tool settings before the tool is initiated.\n\n**Conflicts**\n\nAlmost all are already taken like the typical F for brush size changes. It's not clear what shortcut can be used. \nAlso any shortcut that would be available must then be exclusively used for those brush tools to avoid any conflicts. \n\n**Solutions**\n\n1. Find or make an available shortcut for brush tools radius. But this shortcut then needs to be left exclusive of those tools.\n2. Override needed shortcuts when brush tool is used (In this case F for the radius). This does introduce difficulties and extra tool switching in edit mode though. \n3. Reuse the shortcut C that is used for the Circle Select Tool to change the radius once the tool is active. This will be awkward and incompatible with future tools that will work similar though.\n\n## Open Topics\n\n- Can it be achieved to use both solutions to improve brush like tools?\n- Are there possibly other ways of solving the conflicts in proposal 2?\n- For proposal 1, what shortcuts could be better for adjusting the brush size? + & - are on the numpad and the brackets are too far to the right and on for example German keyboard layouts not very accessible.", "Touchscreen 'Continuous Grab'\nOperating system: Linux-4.15.0-54-generic-x86_64-with-debian-buster-sid 64 Bits\nGraphics card: Mesa DRI Intel(R) Haswell Mobile Intel Open Source Technology Center 4.5 (Core Profile) Mesa 19.0.2\n(bug also tested on Windows 10)\n\n\nBroken: version: 2.80 (sub 74)\nWorked:\n\n\n* Activate a gizmo using the **touchscreen** on a computer.

These will just be referred to as *thing* in this task to avoid having to repeat that entire list.\n\nThe *Selected* and *Active* states are independent, so there are four states a thing can be in:\n\n| | Not Selected | Selected |\n| -- | -- | -- |\n| Not Active | x | x |\n| Active | x | x |\n\n**Problem**\n\nThere are two states possible that can cause issues:\n1. **There are *Selected* things, but none of them is *Active*:** a sidebar/numerical/properties panel will not show information, and generally be empty without explanation why.\n2. **There is an *Active* thing, but it is not *Selected*:** this is not shown in the UI, as there is no separate color for this situation; all *Active* things are shown the same way regardless of them being *Selected* or not. This causes confusion and unexpected behaviour, and also doesn't allow for an actual clear use of this possibility.\n\n**Related Reports**\n\nThese reports are examples of confusing situations where the disconnect between *Active* and *Selected*. The list is not exhaustive, and may be expanded later.\n\n- #14429 (selected bone is not active)\n- #65219 (Objects don't become active object if they are selected by a box)\n- #68647 (objects selected using box select cannot be moved to collection if there is no active object)\n- #81922 (The Graph Editor doesn't show any curve of the Armature (if in Pose mode, but armature unselected, with box/circle/lasso tools))\n\n**Proposal**\n\nThis design task proposes linking *Active* and *Selected* such that:\n1. If there are *Selected* things, there is always one of those that is the *Active* thing.\n2. If a thing is *Active*, it is also always *Selected*.\n\n**Hurdles to Overcome**\n\nRule 1. above requires that one of the selected things is marked active. There is not always a unique, obvious choice here, for example when box-selecting multiple things at the same time. In this case the choice should at least be consistent so that users know what to expect after a while. The thing closest to the mouse cursor (when using the mouse to select) could be a reasonable choice.\n\nRule 2. above can be dealt with in various ways:\n- Create a function that returns the *Active* thing, and make it return nil when that thing is not also *Selected*. This is what was implemented for the Active Keyframe (983ad4210b). This has the downside that now nothing is active, breaking rule 1 and forcing the selection-changing code to pick another thing to become *Active*.\n- Refuse deselection of the *Active* thing.\n- ... something more elegant.\n\n**Goal of this Design Task**\n\nThe goal of this design task is to answer the following questions:\n- Is there an agreement that the current situation causes issues, and that having a stronger correlation between *Active* and *Selected* is a good thing?\n- Is there an agreement that the proposed two rules are the way to go?\n- How do we implement these rules in a way that makes sense to artists?\n- Can we implement this in a way that can be reused by all the affected parts?

This design variant is intended to treat the sampling of values from calculated curves as a new attribute-based сontext.\n| [2022-08-01 14-00-56 (video-converter.com).mp4](2022-08-01_14-00-56__video-converter.com_.mp4) |    |\n| -- | -- |\nThe crux of the problem is that a random attribute, when sampled, must be able to have a position behavior. Other behaviors are not covered yet, but may be added later.\nSampling attributes do not belong to the curve and have their own size. Their interpolation may not be linear, but based on the type of curve, which increases the speed for large objects.\n\nExample: sampling a random vector from curve points. You want the vector to keep its length. But even the original implementation of normals kept the length just because of the normalization. Nonlinear interpolation in spline space for a vector has the ability to rotate it without loss of length and incorrect deformations.\n\nOr you want to sample a color. You can set the color for the breakpoints and... Whoa, those are just linear transitions! Handles cannot be used. They are not a domain and this design does not violate that. Simply by sampling an attribute, you can sample it not only from breakpoints, but from handles!\n\nAlso, in addition to entering an attribute as the domain of the sampled curve, a segment data node is offered. This low-level node is for primary access to cache data. The sampled attribute input node uses this as its signature. But it can also be useful for the user to be able to use this data, for example, to visualize the operation of a bezier curve.\n\nWhen sampling, 3 types of values must be present in the scope of the context:\n - Curve data obtained from the visible version of the curve\n - Curve data sampled from its points and handles\n - Sampling destination data. To keep things simple, if multiple post-sampling values are going to be used with geometry definitions, it's best to do this before the sampling node to keep the output of the node to a minimum.\n\nAlso sampling features:\n1. The option of sampling a vector in normal/target space + sample position can be used as a variant of the curve mesh deformation\n2. Sampling at an arbitrary point creates freedom to obtain information about the curvature of the surface.\n\n---\nCurve Input:\n - Spline type (Select current type curves / index of type)\n - Select Spline By Type (By type index)\n\n---\nChanged Nodes:\n - Sample Curve\n - Input:\n - Curve\n - Factor / Length\n - Curve (Index)\n - Attribute (Random type) (use SampleCurveContext)\n - Output:\n - Value (Random type)\n```\n\n```\n - Position:\n - In SampleCurveContext return evaluated_positions\n - Normal:\n - Same Position\n - Curve Tangent:\n - Move TangentFieldInput to Fields Input and add it in SampleCurveContext same position\n - Index:\n - Same position.

[ "UI: Linux & Mac Support for Clipboard Copy/Paste Images\nAs of the merge of #105833 Windows users can copy and paste images between Blender and other applications. That PR should have made it fairly easy to add similar support for other platforms.\n\nNot shown in #105833 (added later) is that each platform has a \"Capabilities\" flag that indicates that some optional features are supported. For Mac, for example, you can open up intern/ghost/intern/GHOST_SystemCocoa.mm. There is a getCapabilities() function and you can just remove `GHOST_kCapabilityClipboardImages` from that list of things not supported.\n\nThen you are going to declare a few functions in `GHOST_WindowCocoa.hh` and define them in `GHOST_WindowCocoa.mm`, using #105833 as a guide. `GHOST_hasClipboardImage` is meant to return true if the system clipboard contains a format that you are able to read and use. In the unlikely event that your platform does not provide this information you could just return true as that is only used to enable/disable the menu item.\n\n`putClipboardImage` gives you an array of bytes in RGBA order, and a width and height of the image buffer. The data will be without padding, so 4 X width X height of bytes (0-255 per channel). You just need to massage it into whatever format your platform wants and put it on the system clipboard. Returning true if you are able to do so.\n\nWith `getClipboardImage` you need to confirm that there is indeed an image available, get that image from the system clipboard. Set *r_width and *r_height to the dimensions of the image. Then return a pointer to the image data as an array of RGBA bytes without padding. Use 255 for Alpha if your image does not support it. The memory that you malloc for the buffer will be managed by the caller of the function.\n\nNote that the Windows implementation in `GHOST_SystemWin32.cc` is probably much more complicated that you will probably have to write. Windows has a long and strange history with clipboard formats and support for alpha. Implementations on other platforms could be extremely trivial in comparison.\n\n", "VSE strip can't be seen with frame all\nOperating system:\t\tWindows 7\nGPU:\t\t\t\tRadeon Vega 64\nGPU Software Version:\t20.4.2 (2020.0515.1537.28108)\nCPU:\t\t\t\tIntel Core i7-5960X\n\n**Blender Version(s)**\n*(listed are versions tested)*\n\nWorking:\t\t\t\t`2.79 (sub 00), branch: master, commit date: 2018-03-22 14:10, hash: f4dc9f9d68b, type: Release, build date: 2018-03-22, 09:59 AM`\nBroken:\t\t\t\t` blender-2.90.0-ba2d1c889819-windows64` (BF Build Bot)\n\n\nChannel 32 can't been seen with Frame All\n\n\n|  |  |\n| -- | -- |\n\n\nHave at least 2.00 Display Scaling\n\n[Channel_32.blend](Channel_32.blend)", "GP Fill Tool not working on Mac with Metal GPU Backend\nOperating system: macOS-13.4-x86_64-i386-64bit 64 Bits\nGraphics card: AMD Radeon Pro 5500M OpenGL Engine ATI Technologies Inc. 4.1 ATI-4.12.7\n\nBroken: version: 3.5.1\n\nWhen my GPU Backend is set to Metal, the Fill Tool in Grease Pencil is not working.

folder includes an not reachable Alias | MacOS\nOperating system: 13.5.2 (22G91)\nMachine: Apple Macbook Pro M2 Max\n\n3.6.2 - This has been happening before, I'm just reporting it now.\n\nWe have been using an Alias of our flamenco root folder called \"_flamenco\" on our Desktops for a while now. This error is NOT connected to flamenco issues, but I figured I add this for completeness.\n\nAlias is at:\n`/Users/USERACCOUNT/Desktop/\n`\nAlias points to:\n`/Volumes/Files/_flamenco\n`\n\nThis Files server is only reachable in local – physical – network, so if no cable is attached to the machine the connection can not be established.\n\nEvery time I select the Blender File Browser and open the Desktop folder, Blender will hang, freeze or crash.

More info:\n- Views\n- #98560 (UI Views: General ToDo's)\n- #95653 (Split Asset and File Browser frontend, implement Grid View)\n\nThe Asset Browser should be split off from the File Browser and the file-list backend for a number of important reasons. As part of that a grid view is being developed.\n\nOnly doing this and not doing this together with rewriting the File Browser UI raised some concerns for @mont29. So together with him it was decided that both should be looked at. At some point we have to prioritize addressing technical debt too, and not just work on shiny new things. Otherwise we let the code paths diverge significantly, with no plans to address the effective duplication. So both browsers should be ported short-term.\n\n----\n\n**Thumbnail display mode Todo's:**\n- - [ ] Use grid view for drawing thumbnail mode (initial work done in 3a97c4056f)\n- - [ ] Selection in views (click-select, box select, walk select, etc.)\n- - [ ] Double click to open\n- - [ ] Dragging files\n- - [ ] Context menu\n- - [ ] Renaming\n- - [ ] Remove old code (selection, operators, drawing, ...)\n- - [ ] \"Composed\" icons as buttons/widgets  Current code just draws them in-place, but views use the button/widget system.

Similar problem to the above.\n\nThe other display modes should also be ported to views, since otherwise interaction code (selection, renaming, context menu, ...) would have to be duplicated.

This also makes the list shorter so that it can better accommodate #104678.\n\n\n\nFor the Edit menu we can group the items slightly better by making \"Undo History\" a part of the Undo/Redo group. And also make it clear that \"Adjust Last Operation\" is the same that is done when \"Repeat Last\" and is part of repeat history:\n\n\n\nI'd like for the Help menu to look a bit simpler by following our existing recommendations of not showing repeating item icons.

It has been reported here by many people but I've never seen anyone mention the following which I think could be helpful. I always work with a second window on another screen with just a UV Editor open which I think has something to do with the issue.\n\nFor example, in a new scene, start with the Draw brush active and change to the Grab brush then make three brushstrokes on the corner of the cube with it to pull it out. Pressing undo once will only remove the last Grab brushstroke as expected but also revert the active brush to the Draw brush which is not expected.\n\nAfter loading factory settings, the problem doesn't exist. What causes it to happen is if you add an additional New Main Window and set it to the UV Editing workspace and combine the UV Editor area and the 3D Viewport area to make just one large UV Editor area. Repeating the previous steps mentioned in the Sculpting workspace then causes the issue to happen.\n\nThere is some inconsistency with what happens afterwards with regards to changing the windows, workspaces and areas around. It seems various combinations can cause this to happen but the following steps should consistently replicate the issue for anyone on factory settings.\n\n - File > Defaults > Load Factory Settings\n - Window > New Main Window\n\n - On the New Main Window, select the UV Editing workspace\n - Combine the two main areas so only the UV Editor area remains, covering most of the workspace, and the 3D Viewport area is removed\n\n - On the original Main Window, select the Sculpting workspace\n - Select the Grab brush\n - Make three brushstrokes\n - Press undo once\n - Observe as one brushstroke is removed as expected but the brush type is also changed back to the default Draw brush\n\nAdditional observation:\n - Close the New Main Window that has the UV Editor open\n\n - On the original Main

GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 431.07\n\nBroken: version: 3.0.0\nWorked: Never\n\nWhen using the turntable there is a fixed axis around which the viewport always orbits (the Z axis when the viewport hasn't been rolled).\nWhat happens is that Blender rolls this fixed axis with the viewport, so that when you orbit up/ down it does that using the new rolled fixed axis.\nHowever it does not roll the left/right orbiting directions (whatever you call them) with the viewport, meaning that, in my example, it creates an issue akin to gimbal lock where orbiting up/down will cause the same rotation of the viewport effectively making it lose one degree of freedom.\n\nI don't know the reason why Blender seems to behave in an unpredictable manner when orbiting with the mouse, but when orbiting with the numpad keys it confirms that we do indeed lose one degree of freedom as both Numpad {key 4} and {key 8} both cause an upward rotation of the viewport and both Numpad {key 2} and {key 6} cause a downward rotation of the viewport.\n\nSo to fix the issue all that needs to be done is to roll the left/right orbiting directions with the viewport and fixed axis.\n\n**Edit:**\nIt seems my original report focuses to much on the special case where the viewport has been rotated by exactly 90 degrees, causing it to lose one degree of freedom.\nHowever this is just a special case, the main issue is that whenever the viewport is rolled only the fixed axis is rolled, while the left/right orbiting axis(whatever you call them) is not.\nWhat you normally would expect when orbiting left/right that it orbits perpendicular to when you orbit up/down.\nBut since the left/right orbiting axis is not rolled, it meets the fixed axis at an angle other than 90 degrees, causing very unintuitive viewport behavior.\nOf course unless the viewport is rolled by exactly 90 degrees it is still technically possible to axis any viewing direction, however trying to do so will pose quite a challenge to the user.\n\n\n**For loss of one degree of freedom:**\n\n- Open new Blender file (Make sure to use turntable orbit method).\n- Roll the viewport by e.g. 90 degrees using {key shift 4} or {key shift 6}\n- Try orbiting the viewport with the mouse or the Numpad {key 2} {key 4} {key 6} {key 8} keys.\n\n**To see the unintuitive behavior:**\n\n- Open new Blender file (Make sure to use turntable orbit method).\n- Roll the viewport by any number of degrees using {key shift 4} or {key shift 6}\n- Try orbiting the viewport with the mouse or the Numpad {key 2} {key 4} {key 6} {key 8} keys.\n", "Modifiers added in edit mode are undone out of order if you go back to object mode\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: GeForce GTX 1070 with

[ "UI Code Quality: General, Smaller Changes\n## UI Code Quality: General, Smaller Changes\n\nNOTE: This is a proposal, not an agreed on plan.\n\n**Naming conventions**\n\nWe should avoid ambiguous names. We should also avoid abbreviations, esp. extreme ones, for variables with non-small scope. That should further remove ambiguity and make code more readable.\n\nFor example:\n\n| | Type | Old naming (convention) | Proposed\n| -- | ---- | --------------------- | --------\n| {icon check-square-o} | `ARegion` | `ar` | `region`\n| {icon check-square-o} | `ScrArea` | `sa` | `area`\n| {icon check-square-o} | `bScreen` | `sc`, `scr` | `screen`\n| {icon square-o} | `PanelType` | `pt` | `panel_type`\n| {icon square-o} | `MenuType` | `mt` | `menu_type`\n| {icon square-o} | `HeaderType` | `ht` | `header_type`\n| {icon square-o} | `ColorBand` | `coba` | `color_band`\n| {icon check-square-o} | `ExtensionRNA` | `ext` | `rna_extension`\n| {icon square-o} | `int` | `x1`, `x2`, `y1`, `y2` | `xmin`, `width`, `ymin`, `height`\n\nNote that all these examples can be changed without touching DNA (AFAICS).\n\nFurther:\n- [ ] `uiListDyn` -> `uiList_Runtime` \n\n**Various**\n\n* Add iterators for screen data. E.g. iterating all regions (visible or not, including popups and global area regions), iterating all areas (visible or not, including all global areas), iterating all screen regions (as often done by versioning), etc. Could be done in both C (macro) and C++ ([range-based for loop ](range-for))\n* Introduce wrappers for commonly bundled variables (e.g. `PointerRNA` & `PropertyRNA`, `wmOperatorType` & `PointerRNA`, `ScrArea` & `ARegion`).\n* Split up bigger, \"generic\" types. For example `uiBut` contains data that only applies to certain button-types. `uiButTab` is an example of how this can be avoided.\n* Wrap related struct members into nested structs. E.g. rather than `uiBut.editstr`, `uiBut.editval`, `uiBut.editvec`, etc, it could be `uiBut.edit_values.foo`.\n* Replace booleans in parameter lists with enums. Having a parameter list like `foo(true, false, false)` is cumbersome to use (what does each boolean mean) and leads to mistakes (using wrong order of booleans). It's better to be explicit what each value refers to by using enum types. Bitflags are also an option.\n* Remove old game-engine leftovers from Ghost, e.g. `GHOST_FullScreen()`, `GHOST_EndFullscreen()`, embedder windows (`GHOST_TEmbedderWindowID` + non-dialog child windows)\n* Split big functions into more manageable chunks.\n* Add `const` where applicable\n* Of course improving naming, comments and documentation is always a good idea!\n* Use `EVT_` prefix for all event types, to complete work started in [D7164](D7164).", "Toolbar hotkeys can change unintentionally\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce GTX 970/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 452.06\n\nBroken: version: 2.91.0\n\n**Description**\nToolbar hotkeys can change unintentionally.

[ "Proposal to change loop-cut behavior\nCurrently, loopcut is done in 2 steps.\n\n- pick the loop to cut.\n- slide the edge loop.\n\nIn some ways this is good, you make 2 separate decisions quickly without fidgeting with the cursor to put a loop in some place which might be difficult to locate exactly.\n\nCurrently the cut is always exactly in the middle, this isn't always a bad thing - sometimes you want a cut in the middle so in that case you can simply do `Ctrl+R, LMB,LMB`\n\nThis design ticket proposed that it be changed so the initial pink-preview loop is aligned to the mouse cursor, this way the default behavior would be to add where you click, and if you want the loop to be exactly centered you could hold `Ctrl` to snap it to the center.\n\nWe can also make it so holding `Ctrl` while selecting a loop keeps the existing behavior. (This matches knife's midpoint snapping).\n\nThe only drawbacks I can think of are...\n- if you prefer old behavior as default and are adding a lot of central loop cuts.\n- if you want to add a loop where many edges meet or overlap, its can be hard to select the right edge and the right % in one step, In that case you can still *add-and-slide*, but this behavior would mean users would get into a habit of adding directly and double clicking, and in some cases there is a bit of a conflict attempting to make both decisions in one step.\n- Behavior with multi-cut - I would match current behavior with multi-cut and slide, but I can imagine this would feel a bit awkward from a user perspective.\n", "2d curve bevel ignores direction iff the curve is cyclic\nOperating system: Linux-5.4.0-89-generic-x86_64-with-glibc2.31 64 Bits\nGraphics card: NVIDIA GeForce RTX 2070 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 470.74\n\nBroken: version: 2.93.5\nWorked: unknown\n\n\nWhen a 2D curve is NOT cyclic, reversing the direction of segments changes the orientation of the bevel.

However there are some details in its application that need discussing.\n\n## Scope Issue\n\nThe primary design question is which operations should react to layers being locked, balancing mainly implementation complexity and the effectiveness and convenience of the feature.\n\nIn implementing the prototype I decided that the main criteria should be:\n\n* Operations that affect vertex positions, and thus shape keys.\n\n* Operations where the shape key selection matters:\n\n For example, applying object mode transformation updates all shape keys. Thus the selection doesn't really matter, and respecting locks would inconvenience the user that is working on the scene layout, rather than individual object details.\n\n* Deform-only operations:\n\n Even though selection may affect the final vertex positions, operations that change topology necessarily change all shape keys. For that reason, topology manipulation also belongs in an earlier stage of the design pipeline than shape key creation, even though it may be necessary to do it later sometimes for various reasons. Finally, topology change is seldom not accompanied by using transformation operators that respect the locks.\n\n### Current Scope\n\nThis is the current scope of the checks in the prototype:\n\n* All Edit Mode <u>transformation</u> operations.\n\n Specifically, everything invoking the generic transform system initialization code.\n\n* All <u>Sculpt brushes</u> that affect vertices, and not colors or masks.\n\n Specifically, everything invoking the generic brush stroke initialization code.\n\n* <u>Smooth</u> and <u>Laplacian Smooth</u> operators in Edit Mode.\n* <u>Blend From Shape</u> operator in Edit Mode.\n* <u>Propagate To All Shapes</u> operator in Edit Mode.\n\n This one is a bit of a problem, because technically shape selection doesn't matter here: it snaps all shape keys to the current position. However currently I implemented a check to abort if any shape key is locked on the principle that it is a shape key operation. Maybe it should only check the main Basis, or work in some other way.\n\n* <u>Mirror Shape</u> and deleting shape keys.\n\n* A few other operators...\n\nThis [spreadsheet](edit?usp=sharing) containts an exact listing of which operators should and actually do check for locks.\n\n# Discussion\n\nIt is necessary to discuss whether the main criteria, or this specific list needs changing. For instance, I'm not confident that I remembered all operations that match the criteria for the checks.\n\nAnother minor design point is whether attempting to edit a locked layer should be an error (shows a message under the cursor) or a warning (appears in the status line).\n\nSince the checks are done by operators rather than low-level code, add-ons would have to implement them too where relevant. I wonder how many would be affected, and whether some API additions to help them do that easily would be necessary.\n\nThere have also been some questions raised in #104463, like:\n\n> - Are shape keys a special case? (is there other data we might want to lock).\n> - Is the current implementation disallowing editing in all anticipated situations? There seems to be quite a few ways to transform vertices that aren't included here, applying transform, moving object origins, ... to name a couple, probably other mesh tools too. It may feel like an incomplete feature if these are left out, yet, this means we need to add check in many more places.\n> - Are there ways this can be implemented in a way that doesn't frustrate users. For example, you load someone elses file, select objects and want to apply transform. If they have locked a shepe-key it could mean having to manually select and disable the the locks. Users may request a ways to disable locks on all selected objects, maybe going along in this direction is fine, but we can anticipate some of these issues and consider functionality that doesn't add unnecessary overhead. \n", "Child Object jumps away with changing the parent bone\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 451.48\n\nBroken: version: 2.91.0 Alpha\n\nWhen i parent an object to a bone, and change the parent in the object properties in the relations panel, then the child object jumps around.

It also may be nice to allow setting overrides at several different levels of abstraction.\n\nThus:\n\n* Allow an optional default value that would be returned by the variable if the referenced property doesn't exist, instead of failing with an error.\n\n* Allow fallback from Layer to Scene, and then World: one World can be used by multiple Scenes, which can have multiple Layers.\n\nSince this all only makes sense for *custom* properties, maybe it can be a new mode specifically aimed at them, e.g. some kind of \"Layer/Scene/World Custom Property\", which has options for the custom property name (without the `[\"...\"]` quoting), channel index (for vectors), and default value.\n\nThese are things missing for the new driver things to fully cover the features of the View Layer mode of the Attribute material node." ]

I compare it to the Curve Deform modifier as an example of proper deformation. Now, you may say it's an unfair comparison given that curves have an explicit twist that you can modify, unlike hairs. But even without controlling the initial twist of the hair, it's broken in a couple of ways.\n\nFirst, it deforms the mesh unevenly, with some vertices twisting more than others, even in a case where vertices are completely equidistant around the origin and both origins are aligned, like the cube in this image. The selected face and the edgeloop here should be squares but aren't, unlike in the curve deform modifier \nSecond, when changing the length with the Position Slider, the whole thing seems to change twist at once. Instead of having a consistent twist on each point of the path [Particle Instance Mod bug2.mp4](Particle_Instance_Mod_bug2.mp4)\nAs a side note, when using Along Path, finding how to orient your mesh to the hair is unintuitive, always using the global Y axis as the length axis in which I added subdivisions but then twisting weirdly when changing the Axis option in the modifier, I settled for Z in this example.\n\n\nAttached is the same file used in the video, you can open it and move the Position slider in the Particle Instance Modifier, the scale of the Curve Deform modifier example is driven by it so you can see both changing in real time.\n\n[ParticleInstanceTwistBug.blend](ParticleInstanceTwistBug.blend)\n\nWhy do I think this is happening? Well, if you select the object with the particle system, go to the particle properties, and change the length of the hair under the Render>Timing>End subpanel, you can see the problem is the same, basically the twist changes with length. Maybe the modifier should do something different and get the twist from the whole length particle and then scale the mesh instance before deforming or something like that, idk\n\n", "Geometry Nodes Inputs `is_animatable` Property Incorrectly Returns False\nOperating system: Windows-10-10.0.22000-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 3090/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 516.59\n\nBroken: version: 3.3.0 Alpha\n\nGeometry Nodes inputs' context menus ([WM_MT_button_context ](bpy.types.Menu.html#extending-the-button-context-menu)) incorrectly show the inputs' `is_animatable` property as `False` when the property does accept keyframes (see screenshot, attached).\n\n\n - Open the attached .blend file (attached, below)\n - Run the script in the Text Editor\n - Right-click the Input property of the Cube's Geometry Nodes Modifier\n - Open the System Console to see the `is_animatable` property of `context.button_prop` is `False`\n[is_animatable.blend](is_animatable.blend)", "Normal Map gets inverted in Edit mode\nOperating system: Linux-5.3.0-7642-generic-x86_64-with-debian-buster-sid 64 Bits\nGraphics card: GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 440.44\n\nBroken: version: 2.83 (sub 13)\n\nFor some reason having material shading enabled and entering edit mode inverts the normal map.\n[2020-04-14 14-01-54.mp4](2020-04-14_14-01-54.mp4)\n\n1.

In order to increase the validation and testability it was chosen to start with compute shader. Compute shaders are already being tested using GTEST. #104518 adds initial support for compute shaders and the first hand full of test cases.\n\nAfter #104518 landed the development can scatter to improve the resource handling of vulkan.\n- [x] VKStorageBuffer\n- [x] VKTexture #105762\n- [x] VKPixelBuffer\n- [x] VKUniformBuffer\n- [x] Support for push constants. #104880\n- [x] Resource submission trackin. #105183\n- [x] Renderdoc integration (used to validate internal workings)\n\nThe plan is to have the major part of this done in 2023Q1. In Q2 we can than focus on the minimum requirements to get Blender running using the Vulkan backend. This will be a highly instable version with a lot of render glitches, it might even be that immediate mode support isn't supported at all.\n- [x] VKFrameBuffer\n- [x] VKIndexBuffer\n- [x] VKVertexBuffer\n- [x] VKBatch\n- [x] Graphics pipeline\n- [x] Offscreen rendering\n- [x] Basic Command Encoding\n\nSee #106224 for the progress of the graphical pipeline and the attached video to demonstrate the current state.\n\nIn Q3 we can focus on implementing all the missing features. Note that at this point we are not optimizing and utilizing Vulkan specific features, but use a least of development effort to get something running.\n- [x] Immediate mode\n- [ ] Fallback for SRGB encoded textures.\n- [x] Fallback for platforms not supporting 1D textures. #104812\n- [ ] AMD doesn't support `VK_FORMAT_X8_D24_UNORM_PACK32`.

Is available in a branch, but requires some more test cases. and should be aligned with the refactoring of VKTexture. #110887\n- [ ] Texture filtering: Current implementation uses a single sampler for all textures.\n- [ ] Depth ranges/clipping: OpenGL and Vulkan uses different depth ranges which renders some UI elements (including the orientation widget) incorrect. Not sure what the best solution for this would be. Try experimenting with `VK_EXT_depth_clip_control` and check availability.\n- [x] Resources of textures and buffers should be deallocated after the next flush/swap.\n- [ ] Add support to use a different GPU for rendering than the one attached to the display. According to the Vulkan specification this should be working out of the box. I expect some semaphore issues/resource issues in GHOST\n- [ ] Add support for barycentric coordinates for devices that don't support it. The extensions became available in vulkan 1.3 but before that time vendors could have implemented their own extension. Unclear what would be the best approach.\n - Only work around and wait until we bump to vulkan 1.3. Workaround isn't supported when using geometry shaders, so we need to check where it is actually required.\n - Allocate 1.3 context and check for official extension\n- [x] Add support for pixel buffers\n- [ ] Add wayland support. Currently when building with wayland you cannot start blender with vulkan.\n- [ ] VKFramebuffer::blit_to should also support stencil and depth aspects.\n\n\nIn Q4 we can slowly stabilize, and add Vulkan specific optimizations to the code-base. Those optimizations are most likely be focussed on synchronizations, reducing overhead of data transfers/conversions. Here is a list of topics we already found as potential candidates to pick up in this quarter.\n- [ ] Use descriptor set per resource frequency\n- [ ] Use descriptor buffers (single ringbuffer)\n- [ ] Store static Vertex buffers/Index buffers on GPU memory\n- [ ] Auto include pipeline and resource barriers based on the commands inside the command buffer and the description of the ShaderCreateInfos. Might require changes to extract more detailed resource usage. MTL does this automatically, but VK this needs to be done manually.

On the same hair object there can be multiple guide curves (\"eyebrows\", \"hair\", \"eyelashes\" etc). Guide curves are the curves are what the user grooms with the particle brush. The guide curves are sourced into the node tree graph via an input node.\n\n**Growth mesh**\nThis is the mesh that the guide curves are attached to.\n\n**Node tree**\nThis is a slot that referers to the node tree containing the nodes for creating and deforming the instanced hair curves. See design task #78515 (Hair object - Node types design) for more info regarding hair object node design\n\n**Hair simulation properties**\nI don’t currently have a strong opinion about where to place simulation related controls/UI. Perhaps this could be integrated somehow with particle nodes? See example of **simulation influence node** in #78515 (Hair object - Node types design). We should check with @JacquesLucke, since he is working on particle nodes and physics.\n\n|||\n| -- | -- |\n\n\n\n---\n## Alembic cache\n\nReading curves from alembic file as hair is supposed to be implemented as noted in the project description #68981 . I've been going back and forth regarding if I think alembic settings should be placed in the Hair object UI or in the Input node in the node network. I ended up with the conclusion that alembic settings should be placed in the hair object node networks **input node**.\n\n\n{[F8664085](image.png), height = 400}\n\n\n---\n**Notes on guide curves geometry data**\n\nThis is likely relatable to \nT76659\n\nDeformed instances\nImagine the blue poly strip on the image to the left is a deformed instance along a guide curve. The goal is to have it conform to the normal of the surface of the growth mesh (head geometry). This type of workflow is important for creating hair for real time rendering (e.g games) or feathers for offline rendering\n\n{[F8664030](image.png), height = 400}\n\n\n\nSometimes the sampled normals from the surface is too noisy (ear area) and needs to be averaged based on neighboring guide curve vertex normals. The smoothing should propably be done with an operator that is triggered by the user.\n\n{[F8664033](image.png), height = 400}\n\n\n**Normal per guide curve vertex**\nTransfer normal vector from growth mesh surface (CYAN) to guide curve vertices. This normal vector is not used for shading, but for aligning tilt/twist of instances to the growth mesh surface. This is very important for creating hair cards for real time graphics/games.\n\nGuide curve vertices that does not get a ray hit from growth mesh surface can inherit normal vector from the closest guide curve vertex that got a ray hit (YELLOW). We could also use this normal vector to displace the guide curves along the normal of the growth mesh surface with the deform node that is described in the Hair object node design T78515\n\nIf transferring normal vectors from the growth mesh is slow, perhaps it’s a good idea to transfer normals with an operator that is run by the user when desired. I guess it’s important to note that we would not want normal transfer to happen post simulation\n\nIt seems likely that this task is related to storing custom data on hair vertices: #76659 (Geometry Attributes Design)\n\n\n\n---\n**Direction per guide curve vertex**\nAnother important vector to use would be the direction of the guide curve. The direction of the last guide curve vertex will need to be inherited from its closest neighbor. The direction could be used by the tilt for deformed instances and also, the deform node that is described here: #78515 (Hair object - Node types design)\n\n\n\n\n---\n## Tangent per guide curve vertex\n\nThe cross product of the transferred surface normal and guide curve direction would result in a tangent. One potential problem is that the transferred surface normal and guide curve direction could sometimes be almost aligned (eg when hair is pointing along the surface normal). I’m not sure how big of a problem that could be. In case the tangent is zero, perhaps it should just get some arbitrary vector? Perhaps pointing along the X-axis?\n\nThe tangent can be used by the deform node that is described here: #78515 (Hair object - Node types design)\n\n\n\n---\n\n## Operators\n\nIMPORTANT: Nodes are to be developed first, so operators will not be a first priority\n\n**select random**\nexisting operator that is extremely useful while grooming. Selects random hair/points \n\n\n**transfer normals from growth mesh**\nTransfer growth mesh normals to guide curves. Vertecies that does not get a ray hit to growth mesh should inherit from closest guide curve vertex on same guide curve. Normals on guide curves can be useful for aligning instanced mesh. Very important for real time hair (eg hair cards) or feathers in off line rendering\n\n\n\n\n\n**smooth guide curve normals**\nsometimes growth mesh normals might be pointing in a lot of different directions (close to an ear for example). Then smoothing out normals can be useful. This is very simililair to **smooth curve tilt** for curves\n\n{[F8664672](image.png), height = 150}\n\n\n\n**create guide curves from curves**\nUseful for interoperability between other softwares. I think it would be useful to rearrange vertex order per guide curve so that vertex index 0 is closest to growth mesh surface. Only the two ends of the curve needs to be sampled to determine which is closer to the growth mesh. This would be very useful for converting hair using old hair system to the new hair system\n\n{[F8664681](image.png), height = 400}\n\n**resample guide curves**\nBased on current selection. Change number of vertices per guide curve. Vertices should always be equally spaced. When going from a low amount of vertices to a higher amount, it might be needed to \"change curvature\" in order to avoid linear interpolation between each new vertex. The current operator **Rekey** does a very good job, but doesn't solve issues where hair vertices that is not evenly spaced per hair.\n\n{[F8664686](image.png), height = 200}\n\n**Create curves from hair nodes**\nConvert current hair node setup to curves. Useful for interoperability with other softwares. Current operator hides in the **particle system modifier**\n\n{[F8664691](image.png), height= 300}}\n\n\n**Tilt normal**\nTilt normal on selected guide curve vertices. Very similair to tilt operator for curves\n\n{[F8664702](image.png), height= 200}\n\n**select by length**\nusable for deleting/pruning very small hairs. Small hairs can sometimes be accidentally too short by using the \"cut brush\"\n\n{[F8664699](image.png), height= 200}\n\n\n**smooth length**\nsmooth length on selected guide curves by sampling surrounding guide curves. This is useful for making sure there are no guide curves that are shorter or longer than they should be\n\n{[F8664705](image.png), height = 200}\n", "GPU subdivision option with subdivision surface modifier collapses geometry (AMD GPU)\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: AMD Radeon HD 7800 Series ATI Technologies Inc. 4.5.14831 Core Profile Context 21.5.2 27.20.20903.8001\n\nBroken: version: 3.1.0 Alpha\n\nSubdivision surface modifier with GPU Subdivision enabled produce geometry that appear to be lost\n\n1.
