terencemace Posted April 17, 2020 Share Posted April 17, 2020 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!

flcc Posted April 17, 2020 Share Posted April 17, 2020 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. noise contriol by noise.hipnc 1 Quote Link to comment Share on other sites More sharing options...
