I’ve noticed that GLTF2Loader is undergoing fairly rapid iteration. Is there work in progress on supporting the new interpolation modes, most interestingly CUBICSPLINE? Of all the improvements from GLTF1 to GLTF2, getting away from densely sampled animation transforms (and the resulting enormous model files) is perhaps the most exciting.
If nobody else is working on this, we may end up taking a pass on it.
CUBICSPLINEinterpolation added with #11825. If you have a test model available, might be good to verify.
