Sounds a little high for my pics. I have very few lights, and the radiosity
is surprisingly quick. I did some trials, and I think it might double my
time. It also made them look kind of a nasty brown (increased shadows) in
places. Maybe I'll do every 10th brick or so, with more in the lower
segments... Hrm
