Animation Retargeting

Updated documentation on retargeting, metahumans & manequinns is coming soon!

Target Mesh​

By default and for all tools, StudioTwin uses its own plugin content skeletal mesh that is located in the StudioTwin plugin Content folder. However, you can opt for a different target mesh for retargeting purposes. In that way, once an animation generated by StudioTwin is applied to the default skeletal mesh, you can then retarget it to your chosen skeletal mesh.

warning

NOTE: Selecting a non-default Target Mesh requires configuring a corresponding Target IK Rig prior to utilizing any tool within the plugin.

Target IKRig​

When selecting a Target Mesh, a Target IK Rig needs to be set. This Target IK Rig has to be associated with the necessary IK Retargeter assets to facilitate the retargeting process.

Configuration for the Motion Generation tools:

  • The target IK Rig has to be associated with an IK Retargeter asset in the following way:
    • Source IK Rig Asset: Set to SMPL IK Rig, found at Plugins/StudioTwin Content/SMPL
    • Target IK Rig Asset: Should be the IK Rig you've selected

Configuration for the Motion Edit tools:

  • Here you will choose the target animation asset that is associated with a skeletal mesh. The required IK Rig needs two associated retargeter assets:
    • The first IK Retargeter is as described above.
    • The second should be an IK Retargeter with inverse behavior:
      • Source IK Rig Asset: Your selected IK Rig.
      • Target IK Rig Asset: SMPL IK Rig, found at Plugins/StudioTwin Content/SMPL.
info

If you choose a Skeletal Mesh to retarget, before generating one or more animations, you can do it after by navigating in the Content Browser, then select the output animation asset(s) you want to retarget, right-click and select Retarget Animation Assets > Duplicate and Retarget Animation Assets.
