yup....I'm just about out of ideas, I think I might just give up on getting
photon mapping to work and go back to bmrt.....sigh...

Before you give up... there is a bug in MegaPov 0.4 that causes similar
problems (but in other circumstances) that has been fixed for 0.5.  If you
could email me the whole scene (maybe a low-triangle version or one where
you use a POV torus primative instead of the mesh object), I'll do my best
to track down the bug and fix it if it still is there.

I've zipped it up, it comes out to a little bit over 2mb, you still want me to
send it?

Is there any way you could export a version of the mesh with a lower polygon
count?
or give the size/coordinates of the object so that I could substitute a
torus in its place?

I did specify a bounding box for the object , that should give you the size of
the object no?

origin point for the object  4.5,8.5,-4
major radius 25.1501
minor radius 8.5
(I may have switched the major and minor radius by accident)
