A couple of pointers:
1. turn off glow auto exposure and reset the glow intensities(as mentioned)
2. make the glow quality setting high( type in 100 ). This parameter adjusts
the size of
the array used for the glow effect. The max size is the same as the output
resolution, and thus
very large values simply clip to this resolution.
Even at the max value for the glow quality there may be aliasing problems
that show up over an animation
for very small glow sources, like stars. Rendering at a higher resolution
and resizing down with filtering can
help.
Perhaps a better way of doing stars is to use the paint effects stars.
Motion blur(i.e. a fast moving camera) also
works well with this method and if one uses the paint effect oversample
feature( render globals ) then the stars
should not twinkle. The paint effects stars use a built in glow( one can use
shader glow with paint effects, but it
is less stable than the built in pfx glow, which works more like light
glows. If the stars are too dark, increase the
global scale of the brush. The pfx starts get very faint when
small(i.e. distant) just like real stars would.

Subject: making stars with particles
Hi,
I have a shot flying in space. For stars, I am using a software render
cloud type partticle with glow and incandescence turned on. However, the
stars flicker throughout the animation.
Does anyone know why this is happening?
Is there a better way to do stars? I tried to use hardware particles but I
can't get any glow effects. The glow attribute doesn't do anything for
harware particles. The incandescence is also not giving much glow, it's
just making them whiter.
If anyone can answer my question or has any advice on making stars w/
particles (i think lights might be too expensive), I would greatly
appreciate it.
Thanks.
Elvira
