Displace surface by noise?

Recommended Posts

Hello all,

I know how to displace a surface, using the volume vop. VDB workflow. The displacement is generated by noise within the volume VOP.

What I am trying to figure out now is how to have the displacement only on certain parts of the surface, only on certain parts of a sphere, for example.

I can create noise on a surface, but how would I have that noise drive the displacement? So white is full displacement, black is none, for example?

Thanks!  T

Multiply first noise with second noise ?
Not sure is it what your after, as it so simple.

By the way is there a reason you want  specificaly use volume.
For a simple surface displace the "displaceAlongNormal" sop do the trick.
easier and lighter.
