Why don't you just raise the brightness value? That's what I do in most of
my radiosity scenes. Recursion limit 20... are you MAD? :-) crop it to 2,
or 3, and try brightness 2, 3... oh and usually it's pretrace_start >=
pretrace_end.
And don't forget to lower your error_bound to something like, say, 0.1.
So run POV-Ray and try something like:
radiosity {
pretrace_start 0.08
pretrace_end 0.01
count 300
error_bound 0.1
recursion_limit 2
brightness 2 /*3... you may want to tune this value together with the
brightness of your source*/
}
