How to change default preview mesh for a skeleton with Python API

Hello,
With Unreal Engine and Python I need to change the preview mesh of an Animation Sequence, how can I do that?

The var is named PreviewMesh in the preview scene settings but I don’t found any way to access and change this var with the Python API.

  • The var preview_pose_asset in unreal.AnimSequence is alway None with a note “// todo:: note that this doesn’t retarget right now”

  • Maybe it preview_mesh in unreal.PersonaPreviewSceneDescription but so how access to unreal.PersonaPreviewSceneDescription from my anim sequence?

Thanks for your help!
