Right-click on your Anim Modifier Blueprint then click Apply Modifier to apply the Anim Modifier and any changes (or Revert Modifier to remove changes).

Your Anim Modifier will be listed as Out of Date until you apply it.

Below is an example of an Anim Modifier that has been applied to a Skeleton asset, indicated by the Skeleton icon.

Any properties that you have set as Instance Editable will be available to edit in the Animation Data Modifiers tab.

In the image above, we define properties that can be used to drive automatic foot syncing.

Inside your Anim Modifier Blueprint, you will want to expose parameters using Instance Editable that you can manipulate within the Animation Tab in the Animation Tools

In the image above, we use a structure variable containing information that we can set for the name of a bone as well as provide an offset.

Inside our Animation Sequence when we implement our Anim Modifier and apply it, we can see our exposed parameters.

In the image above, we enter the names of the bones that we want to include in our Anim Modifier in which to gather animation data (such as Bone Transform) from.

While there are several different nodes available within the Animation Blueprint Library, this section lists some of the more commonly used types within Anim Modifiers.

These nodes enable you to dynamically add Notify or Curve Tracks to the specified Animation Sequence. Once Notify or Curve Tracks have been added, you can add various types of keys or events to those tracks. For example, you may want to Add Float Curve Keys to a Curve Track, Add Animation Notify Events or Add Animation Sync Markers to a Notify Track.

To get Bone Transform data you can use the Get Bone Pose for Frame or Get Bone Pose for Time nodes which will return the Bone Transform for the provided Animation Sequence with the specified Bone Name. Alternatively, you can use the Get Bone Poses for Frame or Get Bone Poses for Time to collect Bone Transforms for a specified array of Bone Names.

When getting Bone Transforms the transform data will be in local space. If you need it to be in component space, you will need to manually convert the transforms.

The Animation Blueprint Library nodes include several helper nodes including nodes for converting frame and time information (Get Time at FrameorGet Frame at Time).
Another node that is useful for getting information is theFind Bone Path to Rootwhich will take an Animation Sequence and a Bone Name (typically the Root Bone) and output a list of Bone Names in a chain.

Advanced Multi-User Networking

The instructions in the Multi-User Editing Quick Start show how to work with the Multi-User Editing system in a simple Local Area Network (LAN), where clients can automatically discover the Multi-User Editing server. However, automatic server discovery is not always possible. Sometimes, you may need to do some extra configuration on the computers that you want to connect through Multi-User Editing.

This page contains some strategies that may help you successfully establish a connection when the Unreal Editor cannot automatically discover your Multi-User Editing server.

If the Unreal Editor and the Multi-User Editing server are on the same LAN and the same subnet, but they aren't able to discover each other automatically, the cause might be that one or both of them is not set to broadcast or listen to multicast traffic on the correct network interface of the computer. To force Unreal Engine to use a specific network interface, you'll need to specify it as the unicast endpoint IP.

To set the unicast endpoint IP address in the Unreal Editor:

From the main menu, select Edit > Project Settings.

In the Project Settings window, go to the Plugins > UDP Messaging section, and find the Transport > Unicast Endpoint setting.

Set the value of this property to the IP address of the network interface you want the Unreal Editor to use. Always use port 0. For example, 192.168.10.73:0.

To set the unicast endpoint IP address for the Multi-User Editing server, you can follow the instructions given above to set up the unicast endpoint for the Unreal Editor, then launch the server from the Toolbar in the Editor. If you launch the server this way, it will automatically use the same unicast IP address as the editor that launched it.

Alternatively, you can follow the instructions below to configure the IP address manually:

If your server is already running, shut it down.

In your Unreal Engine installation folder, go to the Engine/Programs/UnrealMultiUserServer/Saved/Config/<platform> folder, and open the Engine.ini file in a text editor. If that file doesn't already exist, create it.

Add the following block of settings to the file:

Set the value of the UnicastEndpoint setting to the IP address of the network adapter you want the Unreal Editor to use. Always use port 0.

Save the file and restart your server.

If you want to connect an instance of the Unreal Editor to a server that is not on the same subnet, you will need to do some extra configuration for both the server and the Editor. This involves setting up the server with a port for its unicast endpoint, then setting up the Unreal Editor to connect to the server's unicast IP address and port as a static endpoint.

You need to configure your Multi-User server to use a pre-defined port for its unicast endpoint. There are several ways you can accomplish this:

If you want to launch your Multi-User server manually, you can follow the same procedure given in the previous section for setting up the unicast endpoint in the configuration file. However, instead of port 0, use a different port number in the range 50000 - 60000.

If you want to launch your Multi-User server from the Unreal Editor, the easiest approach is to set the port number you want to use in the Server Port setting that you can find in the Project Settings window under the Plugins > Multi-User Editing section. This value will automatically override any port value you set for the unicast endpoint in the Plugins > UDP Messaging section.

Alternatively, you could follow the procedure given in the previous section for setting up the unicast endpoint in the Project Settings window under the Plugins > UDP Messaging section. However, instead of port 0, use a different port number in the range 50000 - 60000.

If you choose this third approach, the server will always use a port number one higher than the one you set. This ensures that there won't be a conflict between the Editor and the server when they run on the same machine. When you configure the static endpoint for your other Unreal Editor instances in the following section, you will need to remember to add one to the port number you set in the Project Settings. For example, if you set 50000 as the port number for the unicast endpoint in the Editor that you use to launch the server, you will need to configure other instances of the Editor to connect to the static endpoint with port 50001.

To make an instance of the Unreal Editor on a different subnet capable of connecting to the server, you need to specify the IP address and port of the server as a static endpoint.

To set up a static endpoint in the Unreal Editor:

From the main menu, select Edit > Project Settings.

In the Project Settings window, go to the Plugins > UDP Messaging section. Expand the advanced settings under the Transport section and find the Static Endpoints setting.
