The list got all munged up into one object, so I have no idea how to separate them.
Each frame of the animation needs to be computed in Mathematica, it is not simply local transformation of some sold part, the entire object is recomputed at each frame, so I need to upload a list of 3D objects to sum up to an animated sequence.
As far as i can see THREE.TDSLoader is basically able to load both files.
This is something THREE.TDSLoader can’t do for you. If you can’t manage to separate the objects by yourself, try to load all representations (objects per frame) as single files.
