Well, render times were not so bad, the image above - which has no post pro - rendered for 21 h on my G5 2x2, while I was working on that machine for some time, too.
Sky simulation, 11 O'clock in Brussels, and way too little absorption on this one (later picts have reduced absorption)
Setup time 10 minutes
I absolutely *love* the sheer quality of lighting.
Tomorrow I'll post some newer picts.
