I just wanted to get an image with nice smooth edges; I tried using a normal
light source, but the sharp shaddow edges didn't fit very well with the
smoothness of the radiosity (patchy as it was). As I say, I think I'll have
to just use normal area lights without radiosity instead.

I'm no expert, but the more I think about the radiosity algorithm, the more
impossible it seems to implement at all! ;-)

That is not even close to what he said. Radiosity-only lighting is a
very specific application of the radiosity feature, one which requires
very large amounts of processing power and careful tuning of settings.
Radiosity and ordinary lighting are not mutually exclusive, they are
complementary. Almost any scene can benefit from radiosity, in my
experience.

Well, it's sure not easy, I'll agree with you there! ;-)

Mmm... well as I say, I've never actually tried to use radiosity before...
Maybe for a different sort of scene it would look good with normal light
sources too... Perhaps I'll try it sometime.
