Best I could come up with is:

Source is at:

Same for me, I guess it's broken, how about re-encoding and posting again
(on an URL)?

Hmmm.... it's just an mpeg-1, or at least I think it is. I tried to avoid
more advanced codecs on the assumption that some people on the newsgroups
wouldn't have them. However, I'll have another look at it and see if
something else works better. (And if it is actually mpeg-1 or not)

Thanks a lot for giving it a shot. It's doesn't really adress my origional
problem (although that's probably because I wasn't specific enough), however
it does seem to ruffle and break up more than my version. I'll have a little
look at the source code now and see if there's anything I might glean from
it. Thanks.

i just went to the source, saved, copied and modified a .par file,
waited and used ppmtompeg on file ppm's, then mplayer
had a play with frame based stuttering to try and add a startup
jitter/judder in the flame length as the engine tries to go to
afterburner, sem to remember a shade of orange in the flame though,
almost road my bike into the kerb at seeing at two aircraft taking off
fully loaded with store's illuminated by their twin engines on
afterburner against a black october sky aka pitch black, my pushbike's
halogen headlight sorta vanished in the rain haze, 1500 yrds
but i don't know how to add an orange tone to the back edge, say 3/4 to
7/8's to the end from th nozzle, first guess trying to add judder did
something strange when trying to add judder, i scaled around the final
object, then i moved it into the union above and it started juddering in
the mpeg, can i generate a mpg 'increment by N frames and adjust clock'
sort of mode, seen it somwhere recntly, a N elongated frame mpg, with
fewer frames, each displayed longer?
OS - debian unstable, occasionly running beta3, else povray official
on debian unstable or mdk9.1

Umm..... I'm afraid I don't have a clue what you're saying. And note, for
the record, that it's not suppose to actually BE fire, just a red energy
which behaves generally like fire.

Anytime! I didn't think I got very close to what you needed, but I
thought maybe the code might help in the ultimate solution somehow :-)

oops - wrong reply - thinking it was 'tuyere.zip' i was replying about,
first line still applies though
tuyere reminds me of a jet on afterburner, so i thought i'd play with
throttle settings.
actually with your source i now have a forest fire with red glow in sky,
rather nice. no idea how it works though.
seem to have acquired an artifact though.......

My source....? I haven't actually posted the source of my animation, you
know....

bad days, worse nights, now add confusion
i did some minor mods to your posted code and generated a mpg
from it, i thought it might be nice with a few logs thrown in,
say as in a castle's log fire. ( think doom/wolfenstein)
put a few in a a randomish circle and some trees (lots) around, you
would i think get a nice night forest fire, would need to add smoke for
a daylight scene of course :-)
welcome to my mods + ini & par files if you want them
