I've got a bunch of objects flying around in 3D space using Particular and I want to have some realistic 3D falloff. The Vanish settings affect the opacity of each object, which doesn't look realistic when objects in different levels of Z space overlap. I need more of a Fill effect, where the objects Fill with black or whatever as they reach back in Z.
A tight deadline means I don't have time to tinker around.. so I was wondering are there any workarounds that can accomplish this? Perhaps a way to makeshift a Z-pass (similar to 3D Element) and then luma matte?
