Hello everyone,
I am trying to grow some particles inside the holes of the geometry and them spreading them all over the surface of the geometry.
I am using volumesample and volumegradient to keep the position on the surface, but for some reasson it is not working.
Can somebody help me understanding whats going on?
Thanks in advance.
I attach photo and file.

I checked out your scene, the volume gradient needed a couple changes make the points project to the surface. When using the ‘primitive name’ signature, a valid name for the volume to sample must be provided. I filled in ‘surface’, and also normalized the output of the gradient, since the gradient is not normalized by default.

Very grateful for the response jsmack !!!
I see you've done a lot of work on it and new interesting things.
I will inspect it in detail
