Hello,

thank you for your replies. I've done some more experiments with different
parameter settings and obtained much better results. brightness and *count
contribute to the most visible differences. Still, I feel that ceiling and
sphere are too dark compared to the other walls (they're all 50% grey). Does
this have to do with the lamp? How do you simulate a 700 cd point light in a 5
m x 5 m room?


Merry Xmas everyone!
