I wanted to do a sphere with different solid colors per polygon. That’s easy to do with a random expression in a primitive SOP, but then the color goes to the primitive. I didn’t find any straightforward way to transfer it to the points, which is where all the action happens.With all the easy hopping between CHOP, SOP and TOP, it’s weird that we can’t hop between primitives, points and verts. I’ll take a shot at scripting it, but a basic attribute transfer node is really necessary.
Should be pretty simple to make a scriptSOP to do exactly what you want - check out the examples in the operator snippet examples, and the related Point/Prim/Attribute wiki pages! Pretty straight forward even with only a basic scripting knowledge.
