Pass
A render pass creates a picture layer of a scene that can be composited with any other
passes to create a complete image. Passes also allow you to quickly re-render a single
layer without re-rendering the entire scene. Later you can composite the rendered passes
using Softimage Illusion, the fully-integrated compositing and effects toolset, or another
compositing tool of your choice.
Each scene can contain as many render passes as you need. When you first create a scene
in Softimage, it has a single pass named Default_pass. This is a "beauty pass" that is set to
render every element of the scene--you can render a single beauty pass or you can render
separate passes. Also, you can use preset passes such as matte, shadow, toon, and highlight,
or you can create your own passes.
