I like it =) One thing I'm wondering, did you disable the ambient lighting in
your scene? Nearly all radiosity enabled scenes use a line like this at the
beginning:
#default { finish { ambient 0 diffuse 1 } }
Sometimes the diffuse varies or is left out. As radiosity is supposed to
replace the ambient global lighting model, anything with ambient > 0 emits
light (as I'm sure you know from your scene.) A hint: put the above line
before any #include lines, at least any that declare textures. Otherwise the
declared textures will get the default non-zero ambient.
Radiosity_Final is often not as dire as the comments make it sound. I've needed
more aggressive settings than that on occasion. I find Radiosity_IndoorHQ to be
the slowest. Its that recursion_limit setting that can slow things down them
most, in my experience. However, its worth the extra time for a final render,
when its needed.
You might want to check out this page, it has a tutorial on what all the
radiosity settings do: http://www.imagico.de/pov/radiosity.html
