TailorTool™:
The TailorTool is a combination plugin + shader for Universe Animator 4.0.x which allows you to perform boolean operations at render time. The package is composed of the TailorPlug (plugin) and the TailorShader (shader). The basic workflow is to link your objects to the TailorPlug, and add the TailorShader to each object.

 

Rendered booleans have a few advantages over "modeled booleans"...
the first one being that you can animate the boolean operation over time. Another advantage, is that textures are taken into account when doing the boolean. Since all the operations are calculated at rendertime, you can also apply booleans to particles!!!

The TailorTool works with solid objects, surfaced objects, and particles too, as well as with bitmap textures and shaders.
