I was thinking about how to use a cvex mat builder to create a vop for both mat and sop,so I can build a procedual shader without rendering.
It is easily to make it success for a attribute vop.
But It isnt work for mat,such as export some parameter for shader and caused principled shader didnt work properly or I linked cvex to collect node,then add principledShader or something else.
I've seen a hip used cvex for building procedual volume shader,shopnet has a node to generate it,but I didn't find a similarly node for polygon.
Can cvex work properly for general shader?Or did I try wrong way?

I don't think surface shaders can import cvex shaders, but I might be wrong.

How you usually do it is
Make VOP subnet based HDA and make sure you are only using nodes compatible with both CVEX and Surface shaders

Then you can use your HDA in both

thanks for yours advice,I will try this way.It looks like a easier controller for sop and mat transformation.
