Hi.

I can see the MaterialVariation LOP has VEX in it so it is CPU only for Karma. Is there an alternative planned at some point so we can have something similar on XPU ?

MaterialVariation node just sets primvars, what precludes using with with XPU? You would need to use a primvar reader in the material of course, but that should work with XPU.

Hi. VEX does not work in XPU so the MaterialVariation LOP will not work. Here is what I have so far. Best. Mark

You seem to be using a primvar reader to read a string and passing to a file input on a texture reader, that won't work with XPU. Primvars going into shaders must be numbers. The material variation node can only be used to change numerical values if using XPU.

To vary the textures going into a shader, there isn't a tool like material variation that will automatically change the paths on nodes inside the shader. The reference node can be used to create reference copies of the material, then the texure file path can be edited on the texture node within each reference. I think I posted an example of this before.

Hi Jsmck

Thanks. I'll have a look for your post. best. Mark

I think this might be it

Thanks!
