Curve Editor

When you want more control over the way your objects are animated, the Curve Editor can be used to modify and fine-tune your keyframes. Using the Curve Editor's graph, you can create new keyframes, edit tangents, and use various built-in tools to adjust your animation curves.

The Curve Editor is used in other tools across the Unreal Editor, such as Niagara, Curve Assets, and Animation Curves. This guide provides an overview of how to use the Curve Editor within Sequencer, however, many of the features and functions shown will still be compatible within other areas of the editor as well.

The Curve Editor can be opened from Sequencer by clicking the Curve Editor button in the Sequencer Toolbar.

Once the Curve Editor is opened, you will see the following view:

The Curve Editor Toolbar contains various commands, tools, and options. These can be found listed in the table below.

Opens a menu where you can set the following commands:

Tangent Visibility, which controls how Tangents are drawn in the graph. You can choose from:

Curve Tooltips, which shows a tooltip for a curve's name, time, and value when hovering your cursor over it in the graph.

Enables keyframe snapping on horizontal (time) increments in the graph.

The snap increments are based on Sequencer's Frames Per Second if you are using the Curve Editor from Sequencer. Otherwise, you can click the nearby dropdown menu to select a custom time-based snapping increment.

Enables keyframe snapping on vertical (value) increments in the graph. You can select the nearby dropdown menu to select a custom value-based snapping increment, as well as adjust the display of the graph lines.

Opens a dropdown menu for selecting which axis to lock keyframe movements to.

Sets the selected keyframes to interpolate automatically, causing the curve's tangents to adjust based on the location of neighboring keyframes in the graph.

Sets the selected keyframes to use user-defined tangent angles. Whenever you adjust a tangent angle, the keyframe will automatically switch to this mode.

Sets the selected keyframes tangents to use broken tangent angles, allowing for keyframes that have different incoming and outgoing tangent angles.

Sets the selected keyframes to use linear tangent angles. This causes the incoming and outgoing tangents to always face their respective neighbors, resulting in abrupt changes when reaching each keyframe.

Sets the selected keyframe to use stepped tangent angles, causing keyframes to maintain their value until reaching the next keyframe.

Sets the selected keyframe to use weighted tangent angles, causing tangents to use user-defined lengths which determines the influence that tangent angle exerts over its neighboring keyframe tangents.

Flattens the tangents of the selected keyframes horizontally.

The Curve Editor Outliner contains header information for all animatable tracks added to your sequence, as well as a track filter and playback controls.

Selecting entries from the list automatically filters and frames the Graph View to only display curves from that selection and any children. You can disable the auto-framing behavior by disabling Auto Frame Curves from the Curve Options toolbar menu.

You can also use the search bar to search for entries to narrow down the list. Any returned results will also include children tracks.

Contents displayed in the outliner are determined by what tracks you have selected from Sequencer. Selecting tracks in the Sequencer window will cause only the selected tracks to appear in the Curve Editor Outliner. Deselecting all tracks in Sequencer will cause all contents to appear in the Curve Editor.

You can disable this selection matching and filtering behavior by disabling Synchronize Curve Editor Selection and Isolate Curve Editor to Selection in the Sequencer Editor Preferences window.

The Curve Editor Graph contains a two-dimensional display of your keyframes, and the interpolated curves generated. The graph plots both Time and Value on the Horizontal and Vertical axes, respectively, and keyframes are positioned in the graph according to those properties.

There are several ways to navigate within the graph, as well as different View Modes you can use for representing curve data.

Use RMB to pan the graph view freely.

Holding Shift + RMB will pan along either the horizontal or vertical axis, depending on the initial direction of your cursor.

Holding Alt + MMB will pan only along the horizontal axis.

Scrolling the mouse wheel will zoom the graph relative to the Playhead.

Holding Alt + RMB will smoothly zoom the graph according to your cursor movement. The zoom pivot is relative to your cursor position upon pressing RMB.

Holding Alt + Shift + RMB will freely zoom the graph according to your cursor movement, which enables scaling time and value axes separately. Moving your cursor up and down will scale the value axis, and moving it left and right will scale the time axis.

The View Modes menu contains different options to visualize your curves.

Absolute View Mode is the default view mode, in which all curves and keyframes are displayed at their exact values in the graph. This mode functions similarly to most animation curve editors.

Stacked View Mode will separate each curve into its own group, and stack them in the graph. Each group's value range is normalized between -1 and 1.

Normalized View Mode will display all curve and keyframe values overlapping along a normalized value range of -1 and 1. This view can be useful if you are wanting to universally scale curve amounts proportionally.

The Curve Editor is primarily used for editing your keyframes and tangents. You can add, remove, or change keyframe locations which affect the curve. You can also edit a keyframe's tangent, and control the incoming and outgoing curve vectors of a keyframe, which also affects the curve. There are also a variety of features and behaviors to help with your editing.

Keyframes can be moved by using LMB and dragging them around the graph. Depending on your Snap settings, it should be possible to move a keyframe anywhere along the time and value axes. You can also use MMB to move selected keyframes relative to your cursor position. This provides an easier way for manipulating keyframes without needing selection accuracy.
