Hi everyone, I'm new to KARMA renderer, and as I see shader mix is not the same as it is in the mantra

so can anyone explain or show me a sample of how am I supposed to do the same thing in KARMA?

Also, that is using the principled shader.
The principled shader is only "approximated" in XPU

The main shading language of choice for XPU is MaterialX, where it is recommended to use the MtlxStandardSurface. In the next version of Houdini, mixing between two MtlxStandardSurface nodes will be supported in XPU.
