To render with alpha transparency you can use +UA in the
command line, and use an output type that supports alpha
tranparency (PNG, TGA).

You can then compose your object layers seperately.

Handling layer interation can be tricky (one object casts
a shadow on another), but you can manage this with
the no_image keyword.  It's OK in many cases to
ignore layer interactions anyways.
