The brightness is more evenly distributed now, since that seems to be the
way real fire is. I've also tweaked the turbulence and I think it looks
better now.
I've made the emitter point move around so the flames don't just come from a
single point. And I've changed the lighting from multiple point lights to a
single area light at the average location of the particles.
I think the fire moves a bit too quick in this animation but I didn't want
to rerender with more frames. I've had to increase the number of media
samples used, so the fire is slower now.
Comments much appreciated!

There seems to be a single brighter frame at one point that sorta ruins the
looping. Also, I must say this looks like when they paste real fire into a
3D scene, so you're doing great on the fire. Work on the rest of the scene.
:) And add radiosity. ;)

Yeah, you could say that. That looks incredible.

That probably sped things up a bit, though the other things might have
slowed it down.

Only a little. The turbulence of the placement of emission adds a lot to
it. It has the flickering flames at the top that appear and disappear as
I'd expect them. It has the appearance of a slightly bigger fire than I'd
expect given the small campfire the scene depicts, but even at that scale
it's *very* close. I'd be proud to have such a fire in a CRPG, for
instance.

I think in one frame the area_light came up high enough to illuminate the
top of those four cylinders. Is that what you mean?

Thanks! :)

Nah, not right now. I find the particle system itself more important.

"Yeah right..."

Ok. I find it a bit difficult to tell exactly how the fire should look at
different scales...

CRPG, what's that again?
