Material names instead of shading groups names

[koen-v]

Hello all,

When writing usd files, we would love to always export a geomsubset ( we dont always need the material). I would love for both the material and the GeomSubset to be named after the material, not after the shading group.

I found this bug report:
#506

Does anyone know how I could easily get the material name instead of the shadinggroup?

Thanks,
Koen
