Hi Axel,

No prob. I just updated pmapdump.c in the CVS. Try that with your original  
(coplanar) caustic pmap.

The automatic sphere radius is a pretty rudimentary guess and often needs  
some manual tweaking. Usually it's too small, but on the upside that  
reduces sphere overlap, which would otherwise slow oconv down. Pmapdump is  
still pretty rough around the edges, even after over a decade... ;^)

Best regards,
