Maybe better to start a new thread for this. I don’t know what I’m looking at for the PG. Can you explain what is broken?
EDIT: I figured out what is wrong.
Here is a fixed version:
glTF Animation Retargeting Demo | Babylon.js Playground (babylonjs.com)
The reason why there is a problem is because the way glTF skeletons work is a bit different now. But the PG code has a bit of a bug in it since it de-parents the meshes instead of what I think is the intention. Once I fixed that, it works well now.
