To me, the fact that radiosity requires MORE ambient light makes no sense to me. Now, if I understand correctly, it calculates bounced light. So direct light should be bouncing and illuminating surfaces not facing the sun. Is ambient light not just a standard uniform brightness? Thusly, with more ambient light, wouldn't that lighten the dark areas uniformally? I ask cause it seems to be the exact OPPOSITE of MicroStation rendering.
