I'm not sure what you mean by that. Of course all the textures are made from
the same pattern, but unique turbulence is added for each particle, so
they're not identical. Maybe I should also vary the colors a bit?

I don't understand this either. I don't have a set of predefined paths, all
the particles react the same way on (inverse) gravity and wind, and besides
that some randomness is added.
I tried using more particles, but it just made the fire and smoke much more
blurred, because more textures were averaged...

Thanks! Never tried Mechwarrior 2 though...

Should be ready in the next animation!

Are they? Oh, I must be wrong about that!
Okay, well looking at it paused it's harder to spot the individual particles
than I thought, the only hint is that each texture has fairly uniform density
across it, so where they overlap that density is doubled and you can spot the
individual bits. If the texture was more transparent towards the edges then it
would hide this effect better.

I don't mean a pre-defined path, I just mean each particle moves seperately, so
where two particles move relative to each other you can see that they're
seperate. You see a parallax effect that immediately gives away the fact that
they're seperate.

That sounds like it would probably make the individual particles harder to see
:)
BTW, it's still a very nice effect, and anything better would take many times
the render time.

Why not? It's like reading a book... Well, okay, like reading ten

Well, then you'll also have to keep backward-compability in mind... Not

You know, another interesting thingy about the way my system works:
I can calculate one set of particles, save their data, reload it as
emitters for another set of particles... But since my system can't keep
track of existant particles constantly (it would be very parsing and
calculating intensive, to know for each particle, which particle has caused
it, and when...), yours and mine could make a very good combination...
Perhaps when yours is out, we can have a combined look at how we can
make them fit together well and easy?

One things is reading it - making changes to it is a different matter. I
wouldn't be able to keep track on lots of small changes without coding them
little by little and testing that they work on the way.

Only if I want to... I think it'll cause too many problems to really ensure
backwards compatibility.

One time for every frame, or once and for all for the entire animation?

We'll see - I'm pretty sure the interfaces are completely different from
each other.

I wasn't really thinking about making major changes, just some
simplifications on certain algorithms, or variable-usage (there are
tons of them right now, and I probably don't need THAT many)
to save some RAM. And testing afterwards is of course a must.

I could go both ways, either for every frame, or once and for all,
though the emitting-objects wouldn't move then (I can only save
a certain time-frame, not actual animations, at least not yet)

I agree to that, but nontheless I could look at your system in order
to make my macros fit yours, and perhaps vice versa? Just that
someone could put your system in a macro of mine, and my
system in a macro of yours (in case your actually supporting
that many macros, I've made it possible for EVERYTHING to
be user-defined with a macro... but I'm not sure if that was
a good idea...)
When I'm back from my civil service course, I'll probably work
on some images and the particle system (docs, algorithms, examples),
so expect some funky (and crappy) ideas when I'm back... ;-)
