Hello, I'm looking for help.

I'm trying to export a USD with ROP USD from solaris and import it in Unreal ( geo, lights, MtlX) I have enabled the USD plugin in Unreal, but I'am having issue with the shaders.

I tried 2 different methods:
- Importing with stage actor ( no shader are imported )
- Importing with a drag and drop, but the diffuse map in not interprated as sRGB ( unreal setup as linear)

I have searched for solutions on Google, Discord, and the SideFX forum, but I haven’t found a clear answer.

Thanks for your advices.

Have you switched the render context to Mtlx in the USD Stage Options menu?
