And YOU call yourself a perfectionist ?
You should be able to tell us, that the time will grow with the logarithm of
the
number of the triangles (if they are saved in octrees, then probably
logbase=8)

to late to change that ? I thought you can send in as many pictures as you

of course, you have normals turned on, in the radiosity-block ... , haven't
you ?
