In addition to Sherry's advice, if you need further help, you could also
post a sample scene to the povray.binaries.images group. Good radiosity
settings are generally very dependent upon the other lighting and objects in
an image. In other words, what works well in one situation will not work
well in another.
Another short answer is simply to keep increasing "count" and keep lowering
"error_bound" until you see something that looks good. That barely
scratches the surface, if you want good quality that renders in a reasonable
time, but it's a good start.
e.g.
global_settings {
assumed_gamma 1.0
radiosity {
count 200
error_bound 1
}
}
Decreasing "error_bound" (imho) will create deeper shadows, whereas
increasing "count" will make smoother shadows (meaning fewer blotchy
spots/artifacts).
