Your OBJ file contains a lot of polygonal faces with more than 3 vertices. PyTorch3D doesn't support them and has to subdivide them into triangles, and it makes an assumption about order when doing so. See https://github.com/facebookresearch/pytorch3d/blob/main/pytorch3d/io/obj_io.py#L126 . I wonder if that assumption isn't valid for your data. I can't think of anything else.

Thanks! That's probably the issue. I'll see if I can fix the problem with some preprocessing.

Just verified that triangulating all faces in blender and then exporting to obj solved this issue.
