Had this happen when anything piped into an ambient occlusion node is
greater than 1. In my case it was a weight map with a factor of 1.2.

Wayne,
Had a similar problem here and I believe after removing one of my
ambient occlusion maps it went away. Not sure if your using AO but
worth mentioning.

*Subject:* Black dots in renders
Searched a bit on the base and found a couple posts but no one really
came to a conclusion as to what actually causes the black 1-4 pixel
sized artifacts to occur. Using a dual, dual core amd box here and
got a ton of them (4-6 per frame) in my last render. Using an ldr
image with one area light casting shadows in the image. Some posts at
the base suggested scene size but I have a single character about the
same size as the default man that ships with XSI so Im guessing it
isnt that. Has anyone else had this occur and if so, any workarounds
you may have come up with apart from hand painting them out frame by
frame. Thanks!

Had the same thing on a single character, and upped the subdivision
step for the effected frames (the difference between the model I was
using at a level2 and a level3 subdivision was pretty much
unnoticable), and re-rendered those again. This has usually worked,
but not always. I was using the dirtmap plugin at the time, but was
getting the black dots in my colour pass. Weird.
