Hello all,
    I have not posted in a long, long time, but now I am back doing some
raytracing and I need some help (go figure..). Anyway, I have been using Max
recently with the Brazil rendering system plug-in, and the results are nice,
but the fact is, I hate modeling in Max. So I have come back to Pov.
    My question is this...The first picture (caustinc_ring_2.jpg) represents
a render I did with Brazil to test its caustics, the second picture
(torus.jpg) is a photon image that I did in MegaPov just trying to get some
caustics as a start. But, as you can see..it looks like absolute crap. Why
is the ring glowing like that, and why are there no caustics in the familiar
parabolic shape?
    Thanks - Oldstench
