Unable to Load Materials in usdview from NVIDIA Default Scene Templates Pack

When trying to open a scene from the Nvidia Default Scene Templates Pack in usdview, I encountered a MaterialBindingAPI warning, and none of the materials loaded properly.

Steps Taken:

  1. Ran usdfixbrokenpixarschemas—this resolved the MaterialBindingAPI warning, but the materials still failed to render.
  2. I then used usdchecker, which reported an invalid shader node in the scene.

Are there additional steps required to fix broken shaders or material bindings? Could this be related to missing plugins or incorrect USD schema definitions?

Any help would be greatly appreciated!

Apparently usdview does not support MDL materials and most content published by NVIDIA only comes with MDL, not also w/ UsdPreviewSurface

Correct-- these assets are currently backed by MDL materials, so won’t visualize in usdview. I don’t have a plan or firm timeline for updating or replacing these assets right now, but will discuss it.
