Wa-hoo! I found a subtle but serious problem with the fundamental way that Anim8or generates samples. Single samples are fine but they can become correlated with subsequent samples of the same value. For example, a reflected surface samples lights twice, once on the original hit and once on the surface hit by the reflection. Correlated samples are bad because the loose some of their "randomness" and can appear as many kind of artifacts. This happens in the Reflective Egg example when the number of samples is a multiple of 4 (like 4, 16, 36) but not nearly as much at other numbers (9, 25, 49) though it still can happen.
I've fixed the problem
