Hi Jill, hi Lars,

I'd like to chuck in my humble 2cents worth and point out that  
abovementioned limitation is the very reason the photon mapping addon was  
developed for RADIANCE. This is precisely what Jill needs. Although it  
won't eliminate the tesselation artifacts, it will simulate the resultant  
caustics more efficiently than virtual light sources.

RADIANCE binaries with photon mapping were available on Francesco  
Anselmo's website, but appear to have been removed from the downloads.  
Anyone have any recent binaries Jill could try out?

Regards,

--Roland
