Thank you. I think maybe I wasn’t clear in my question.
I’m pretty happy using polygonal Boolean and vdb combines.
My real issue is possibly more shader based.
In the image it’s the gold areas I’m trying to replicate. Is there a way to make a selection based on cavities/recesses sovthat I can apply a different material?
Or, in that image is it more likely to be a noise driving a displacement and the same noise masking the gold?

Thanks for that!
Would this work for using meshes generated by vdbs?

Hi all,
I’m a relative newcomer to Houdini (after a few years away) and although I’m getting back into a lot of areas I’ve a roadblock.
I’m trying to work out how to create a particular look, where the outmost parts of an object have one material but recessed and cavities have another. See attached as an example. Basically a tortoise shell kind of thing.

Any ideas to point me in the right direction?

Cheers all.
