unsupported animation target path weights

See original GitHub issue

@kcoley

raise Exception('Unsupported animation target path! {}'.format(target_path))
Exception: Unsupported animation target path! weights

You can download this model from here. buster_drone glTF autoconverted format

To get this animation to build I removed the paths referring to weights in the glTF ascii file. However, the usda animation is distorted.

@kcoley @ox Apple also has some sample python scripts for building usda files as part of their USDPython standalone library v 18.09. I have a live usdz example of skinnedMeshAnimation with weights.

skinnedMeshAnimation skinnedMeshAnimation.py.txt

Another Apple sample usda file soccerBall.usda.txt

Ok, so after a bit more work I managed to:

correctly align blendshape names so they match in the SkelAnimation-defined names and those targeted in each Mesh’s blendShapes token uniform
correctly managed to fetch multiple blend shape weights for each keyframe by passing in the ratio of outputs to input frames

Check out the gist to see a USDA of the AnimatedMorphCube gltf model.
