Damaged UVs of mesh after import?

Hi there!

Ever had the problem that the texture coordinates (UVs) of a mesh arrive wrong in Unity? In my case, they all arrive at {0,0} (I printed them out). I can't find anything wrong with the model in my modeling programthe UVs look Ok there.

I'm importing Maya .ma and .mb models with Unity 3.3 Pro native import.

Forced Re-Import doesn't help, neither does changing the model in Maya and letting Unity import it or creating copies of the mesh-file.

Very strange..

Ok, so I just found a workaround, when I export the geometry via FBX and then import it in Unity. Still... a very strange behavior.

Any idea what could cause this? I'll submit a bug request if manage to pin down the problem.

Thank you
