I dont know if I am going to be clear about my problem, anyway there it is:

I have a concrete node in the surface shader that I want to use also as a displacement, but inside a displacement node I cant have this concrete node.
Is there a way to use the same node as a surface and displacement shader?

Thanks

if you can, post an example hip

Typically displacement is done before shading, therefore you need cut/paste your displacement segments from the surface shader and put them into a displacement one.

Any of the displacement stuff that is being used by the surface node should be exported from the displacement node and imported into the surface one using the import displacement variable VOP.

Thank you very much!
I really appreciate the help.

I´ll post later the results.
