Retargeting fails if avatar mesh is rotated

[Joe_Kerr]

Hi everyone,

May or may not be a bug: https://playground.babylonjs.com/#K1QFZD#5 (retargeting fails if avatar is rotated).

To fix, just zero the transforms before retargeting and revert afterwards. If it is a gltf model, rotation.y needs to be Math.PI.

Best wishes

It’s probably the same problem as here:

Retargeted animation is rotated incorrectly and has hands misaligned

The problem is that for retargeting to work correctly, the rest pose must exactly match between the avatar and the animation. I updated the animation retargeting tool to work with your animation and avatar: [image] You can see that the orientation of the clavicles don’t match (and probably other bones too). I tried to update some bone orientations of the animation and could come up with: It’s not perfect, but it shows it’s possible to make the retargeting process work better by updatin…

The rest pose must be exactly the same for the animation and the mesh for retargeting to work as expected.
