This is almost always due to MaterialBindingAPI not being applied to the asset. Try running usdfixbrokenpixarschemas on that USDZ file (make a backup copy first).

That solved it, thank you! Much appreciated.

Hello everyone,

I’m currently exploring Solaris and ran into an issue that seems relevant to this topic. It also looks like a previous user may have encountered a similar problem.

I’m trying to import a high-poly model from Sketchfab in USDZ format. The model loads correctly, and materials are visible in the Scene Graph, but they are not assigned to the geometry.

If I import the same model in GLB format, the materials are partially assigned, but the textures are missing.

At the same time, the USDZ version of this model displays correctly in NVIDIA Omniverse, including all textures.

Could you please advise if there is a recommended workflow or a specific sequence of steps to properly interpret this type of model in Solaris and correctly apply materials with textures — primarily for rendering with Karma?

Any guidance would be greatly appreciated. This would not only help me better understand Solaris workflows, but could also be useful for other artists facing a similar situation.

I’ve linked a simple test file in case you’d like to inspect the scene structure and import details.

I've been working on XPU all day, and it seems to be running smoothly.
