3D applications are render layer centric because it suits 3D artists. However,
once you import a pre-comp file into Composite, it becomes camera centric
because it is more suitable for the 2D artist. Now you can perform any
compositing work needed on the pre-comp file, and go back and forth between
Composite and the 3D application.
The Composite pre-compositing interoperability supports having a different
set of render passes for each render layer. In our example, Render Layer 1 has
more passes than Render Layer 2. Render Layer 1 only has an Ambient pass
and Render Layer 2 only has a Reflection pass.
For a given render layer, the set of render passes produced by each camera can
be different in a pre-compositing setup. For example, Maya cameras can decide
