Hello and welcome!
Here are some examples with RPM animations imported separately and then applied to avatar with no animation:
- https://playground.babylonjs.com/#78QAXA#11 - with targetConverter
- https://playground.babylonjs.com/#JQLEGG#6 - with ImportAnimations
- https://playground.babylonjs.com/#JQLEGG#13 - with more animations imported
Avatar preparation could be tricky in Blender for the first time, I think I’ll make a separate post how to do it.
