i'd wager with a "fixed" particle generator, you'd then notice the
performance hit in using an iterator compared to your unrolled
version. i am constantly frustrated by the iterator patch.

Ok, so I noticed that actually, in time forward mode, you have to
wait a while (50-70 seconds) to see anything -- the back-and-forth
time is a 20 second span from 50 to 70 (so it never gets close to
0), and jumping to less than that causes the population-count-
changing system to ignore everything (!!!) until time moves
forward again. Fun stuff :)
Wow, thanks for the quick responses on this. It makes sense to me
now why this would be so screwy, I suppose. So, the question now,
is, do I need to just implement my own particle system patch? That
doesn't really bother me: I have a fair-to-middling background in
OpenGL, and am an honest-to-goodness software engineer (although
not generally of this sort...this is just a side hobby.) So writing
my own particle system patch it easy enough. I guess then I would
have finer control over how, precisely, the thing behaves. Still,
it seems I ought not have to, since here's a perfectly reasonable
particle system patch already done for me.
I guess the short of it is: what's the actual solution here? Is
there one besides either a) leave the loop unrolled, or b) write my
own particle system that can handle this?
That's really, really unfortunate, if iterator's are actually so,
well, lame... :P
My other question, then, is whether or not there's a way with the
default particle system patch to make the particles fade in, even just
for a few frames. I don't really like the popping effect when the
system spawns new particles. I played with the settings I saw (setting
the mode on the patch to interpolate size and color didn't do much for
me, including the new settings that revealed.)
Otherwise, any recommendations to make it prettier? I'm just kind of
playing around here. :)
