  Spot-light problems

Humm.. This one's been bothering me a lot the last few weeks. I haven't
sat down and really -worked- at it much, but, yeah. Here it is. I have a
scene where there are four (eight, actually, but only four have
atmospheric_attenuation on) spotlights shining on a single die. I had
been planning on having the die spin around a few times, with the
spotlights doing a bit of a thing around the box the die is inside.
Well, I first got past the rather awkward problem of having
atmosphere-in-a-box, and I rendered the new scene. It was coming along
rather nicely (slow, but it looked nice enough to me).. until I saw
where the spotlights all met. There was some rather nasty lookign
interference there.. anti-aliasing, I think. Mach bands, or something
like that. Anyway, I jacked up the samples and jitter rate, and the
problem is still there. -PLUS-, even weirder, I find, it screwed up the
texture of the box. It ended up with these odd black stripes.. Strange.
Can anyone help me out? It'd be muchly appreciated.

Glenn
