Ok, just ran through those options but no cigar. The problem is that the
camera is moving through the star field resulting in those very unrealistic
BIG particle stars. With regard to the near vanish and fade, that simply
adjusts the opacity as opposed to the size. What's been working really well
for the "classic" warp fly-through is to use a straight gradient and
mapping it across X/Z on the size layer map. That scales up the stars in
the distance and whilst scaling the foreground stars down. However, once
you apply "disperse" and a fractal displace it mixes up the direct
relationship to the gradient.

I was hoping that using a complex OBJ model to generate a mixed star field
would do the trick but unfortunately that option does not allow me to map
the gradient over a specific axis.
