I have been trying to create density falloff with in my vdb volumes. Because of large scales I have been using vdb and the volume geometries that create those vdb are arbitrary asymmetrical shapes. When I was doing my test on a regular spherical object it was easy to find the max distance from surface to center which then I can feed into a fit node in volume Vop. But now I have asymmetrical shapes I am a little stuck. Basically I want a falloff curve which I can control with a spline ramp and have denser core, I have been reading about point cloud and doing some shortest distance calculation from a point to surface but I hope maybe there is a simple way before I jump into complex calculations. Any ideas or suggestions are much appreciated.
