Hi guys,
I can't get "mtlXmix" to work with XPU.. How can I mix material, using texture mask please?

Thank you.

Testing mtlXswitch node, interresting but switch textures, not material.. :/
To be continued..

I'm not aware of Mtlx being able to mix materials at all, just shaders
which is maybe what you are trying to do anyway

so to that point, mixing surface shader in Mtlx in Karma CPU works fine
trying to do that in XPU prints out an error
which is a clear indicator that it is not supported in XPU Alpha yet

Here is a chart that compares Mantra/KarmaCPU/KarmaXPU:

Custom/Layered MaterialX Shaders are Planned for Future Release in XPU.

There is also documentation here
https://www.sidefx.com/docs/houdini/solaris/karma_xpu.html [www.sidefx.com]

It says that the "PBR" nodes are not yet supported by XPU.
https://www.materialx.org/assets/MaterialX.v1.38.PBRSpec.pdf [www.materialx.org] (page 14)

But admittedly there is no easy way for a user to tell which nodes are "PBR" and which are "Standard" :/

Thank you guys!!
