Sample skinned assets without inverseBindMatrices #132

Open emackey opened 1 week ago

The glTF spec says that inverseBindMatrices are optional.

Does this repo contain any sample assets that use skinning without the IBMs? We should probably have a test asset that checks whether this works in client implementations.

FWIW, the third model of https://github.com/KhronosGroup/glTF-Asset-Generator/blob/main/Output/Positive/Animation_Skin/README.md is testing this exact thing.

If you have a model you want to try, I can use Unwrap3D to strip out the inverse bind matrices. It works on all models I have tried.
