Hello!

I made a particle volume out of some mesh and using attribute transfer and attribvop made a noise mask who will mask the gravity influence on those particles. Everything works ok BUT is there some kind of a way to somehow limit my noise mask not to go all the way through my volume but just be isolated on particles that are closer to the surface so I can avoid the whole wolume collapsing down towards the gravity where mask is? In other words, is there a way to limit my mask how deep it can penetrate my volume? Can it be done inside vop?

Have a look at xyzdist (distance to closest prim). Connecting it to a fit range in your vop should get you there.
