Here's a trick I use in my own radiosity-only scenes. Say I have a small
torch flame (emission and absorption media) that, used by itself, would
require a radiosity count of 1000 to give a good smooth lighting effect to
the scene. If I use five of those flames in the scene, I find that I can
reduce the count to (very roughly) 1/5 of that and still get good overall
lighting. The radiosity light "patches" from *all* the flames add together
and nicely overlap. How well this works depends on other factors,
of course -- mainly, whether or not each flame is lighting all
parts of the scene.
