Dear Community,
I have a USD file showing all the materials for the different assets correctly. I want to choose the base color image from a PBR out of the different metallic/roughness… It seems the export functionality in Isaacsim from usd to .fbx is already doing something similar. I would to know if this is actually possible: go over the different texture images provided to a mesh and be able to pick only the basecolor (I want to do that through python scripting)
Thank you for your help
Anthony
Hi there @toninsemaan,
I think since it has been quiet here for some time, you might have better luck in the Omniverse category?
I move the post over there and I am sure you will get some help.
Thanks!
Hi @toninsemaan. Yes, it’s possible. You could traverse you stage and find all the meshes like this: Find All the Prims of a Given Type — Omniverse USD documentation
You can then compute which material is bound to each mesh: Universal Scene Description: UsdShadeMaterialBindingAPI Class Reference
On the OmniPBR shader, for example, the base color texture is found on an attribute named: inputs:diffuse_texture.
Let me know if you need a more concrete example.
