Where does the specialization of the materials happen?

[koen-v]

Hello all,
I am trying to get a export going where materials are re-used instead of specialized. The first step I have, where I export all the uv sets as st*, I was looking trough the code to see where the specialization of the material happens. I found notes in PxrUsdTranslators_FileTextureWriter::PxrUsdTranslators_FileTextureWriter, but I was not sure what to change to re-use materials.

Would it be possible to point me to the code where "shaderball" actually gets specialized to "shaderball_st_st_st_st..." ?

Thanks,
Koen

Sorry for the noise, found
const UsdShadeMaterial& getMaterial(const TfToken& shapeName)
in
lib\mayaUsd\fileio\shading\shadingModeExporterContext.cpp

Thanks
