Are you rendering everything in one pass? If you have a
compositing program like AE, you can render individual parts of
your scene separately and composite later, which makes for
shorter individual renders. Jeremy Birn talks about it at length in
"Digital Lighting and Rendering." It can also give you more
control over the look of your output if you render each indvidual
model in separate passes--a beauty pass, a highlight pass, a
reflections pass, etc.
I just solved a very thorny choreography problem when I realized I
should just render the individual models separately and
alpha-comp them later in AE. The output is only 640 x 480 at 30
fps (no oversampling--I'm only matching to Digital 8, so why
bother?), the objects are simple, and there's only one light, so it
wasn't a question of rendering times at all. But doing each
element separately changes my whole approach to the shot.
I'm sure many of the stills illustrators here will pipe up and say
they do multi-pass renderings all the time and layer the passes
in Photoshop. Same reasons--faster overall rendering times,
more control.
It's even made my wife happier, since I won't be committing
suicide now. ;)
