Is that a Karma XPU limitation at the moment then?

Yes, it currently allows only the mixing of two MtlxStandardSurface nodes.

I see, good to know. Can probably find a workaround then. Thanks!

I'm not sure what issue you have.
But here is an example.
Does it work for you?

Hey,
Yes that example file works on my side as well. I noticed however when I add another MtlxMix node after that one and add another surface mix it fails to render on XPU which is what I did in my project as well to layer different shaders, still works fine on CPU though (attached example). Is that a Karma XPU limitation at the moment then?
Thanks!

you can mix two MtlxStandardSurfaces via a MtlxMix node

Hey brians,
thanks for the reply. That is what I am already using, it works fine in Karma CPU but the same shader renders just grey in XPU currently. I do not get the same error as in H 19.5 saying it doesn't support MtlxMix nodes anymore but it still doesn't render correctly.
Thanks!
