The effect you see when the camera moves could well be
anti-aliasing. When you’re dealing with this kind of very fine detail you’ll
need to turn off the adaptive sampling by bringing the minimum sampling value
up to meet the maximum. 1,1 or 2,2. 3,3 at a very rare pinch. At those high
levels you may want to break it out into a separate pass.

Subject: Starfield Environment Shader
Can anyone point me to a decent one? I've tried the
legacy night shader, but I get strange artifacting when the camera pans or
tilts - a rippling effect across the stars, and some seem to smear into lines
for a few frames. Failing that, I'm considering the old Lightwave
surrounding-sphere-of-single-point-polys technique, but are single point polys
even possible in XSI?
What other approaches are people using in XSI to create their starfields?
