Houdini 16.0.633

Using the layer mix does not seem to be working with materials that i create.

Created a basic setup with noise to diffuse on classic shader then collapsed into a material. Added a parameter for the “Layer”
Parameter type “ Struct” - “ShaderLayer”
Export always and attached to the classic shader layer pin. As in the houdini 16 master class , custom shading.

It just comes up black.

I tried with a metal grate and concrete from the material pallet and it works fine. So there is an issue with my setup.

Anyone have this problem?

Can you attach a scene with your material? I have had success with layering materials, but there are some ‘gotchas’ with material vops in general.

Here is a scene for you.
Thank you
