USD export 2026 - no textures/dependencies

Dear Chaos and Community,

Lately I’ve tried to export some vray content to .USD in max2026.2 - vray 7.2 - Autodesk USD 0.12

I do not find any options or settings to export vray materials’ including dependencies/maps? It was working nicely with the Omniverse Connecter Exporter in max2024 and most vray materials were successfully exported. What am I missing? As usual Autodesk Support is incredibly useless.

Any hint is highly appreciated,

Seems to be working fine. Make sure you’ve enabled the V-Ray Plugin configuration plus the “Export Materials” checkbox. Maybe it’s a pathing issue? Any errors/warnings in the VFB log?

Thanks @hermit.crab ,

My options look exactly like yours, but does it actually collect all resources (texture maps) on your side along with the .usd? In my testasset I’ve loaded a local texture map in a VrayBitmap Node and connected it to the shaders diffuse, absolutely basic.

This is the log:

When I export to USD ASCII It shows the line of the connected texture, but it won’t load in Blender or the Omniverse after import…

Odd. Mind if you send a simplified version of the scene in question (plus the texture)?

Just to be clear - you won’t be able to render V-Ray stuff exported to USD with something other than V-Ray (like Omniverse).
