Usually, the FBXLoader loads the mesh without problems.
On this model however:
38733.zip (3.3 MB)
something is wrong with the mesh positioning.
This is how it supposed to look like. Looks like autodesk’s web viewer uses three-js REVISION 71 but I suspect it does not use three-js FBXLoader as THREE.FBXLoader is undefined.
If you’ll use this three-js FBX viewer you will see how it looks like with THREE.FBXLoader.
Please ignore the colors differences, this model hasn’t been textured yet.

The diamonds position is wrong.
Any suggestions?
