Describe the bug
Most mesh bounding boxes for meshes are calculated correctly, but the occasional box disagrees with vanilla. It should be checked whether this is an error in the original model or not, and if not, the extra edge cases should be accounted for.
Similarly, the bounding sphere calculation is only currently correct for meshes with 3 or 4 vertices. For 5 and above it begins to disagree. The true bounding sphere calculation should be discovered.
