UnrealEngine

Download the Unreal Engine Plugin from here. It currently supports version 5.2.

Place the downloaded plugin into the '..\ UEProject\Plugins' folder. If the project was open during this process, close and reopen it.

In the Content Browser, right-click the Skeleton in the '\Plugin\Sample\MoAModelMeshes' folder and create an Animation Blueprint.

Double-click the created Animation Blueprint and connect Live Link Pose to the Result node.

Select the Live Link Subject.

Select the Live Link Pose and change the Retarget Asset to MoARemapAsset.

Import the model you want to use for another character in MoA UE.

Right-click and create an IK Rig from the Animation menu. Set up the IK Rig by referencing IK_MoA located in '\Plugins\MoALiveLink Content\Sample\Retarget\IK'.

Set up the IK Rig.

Create and set up the IK Retargeter.

Create an Animation Blueprint for the Skeleton you will use.

Connect Retarget Pose From Mesh.

Click Add and add two Skeletal Meshes.

For each Skeletal Mesh, select the MoA Mesh and the mesh of the model you will use. For the Anim Class, assign the Live Link Animation Blueprint to the MoA mesh, and assign the Animation Blueprint created in step 7 to the model mesh.

Click Add and add Live Link Skeletal Animation.

Since the MoA model does not need to be displayed, uncheck Visible in Rendering.

Place the Blueprint in the map and check it.
