Basic Compositing in Reaction			Working with Layers
Chapter 8, Multilayer Compositing and 3D Effects

Once created, you can automatically generate and update compositions based on Maya render layer and pass setups. This accelerates and streamlines the 3D to 2D workflow by allowing the 3D artist to pre-visualize a scene in the form of the final composite while continuing to iterate on and refine only required elements. The format supports different passes per layer and per camera; passes from pairs or sets of cameras can be imported side-by-side within a composition, allowing their dependency graphs to be manipulated in tandem, and making it easy to select pairs of nodes for viewing as stereoscopic output. For more information, see Maya/Toxik Interoperability and 3D Limitations.

General workflow for working with pre-comps:

• Import a Maya scene--see Importing Maya 2008 Render Layers.
