I need a little help with creating a decent engine exhaust for this. Right
now I'm using a light source inside the engine to produce this effect, which
is fairly ok, but some visible exhaust would be better.

Any ideas on how to add it? I haven't had much experience with media; I
manage to screw up scenes when I add it.

BTW, this is a fighter I'm working on for myself, comments welcome on the
design so far.

I don't remember who posted it, but here is a code fragment that makes
engine exhaust using media.  It looks great and I have used it myself.  Hats off
to whomever it was...

//begin code

camera {
  location  <15.0, 15.5, -4.0>
  direction 1.5*z
  right     x*image_width/image_height
  look_at   <0.0, 0.0,  0.0>
}

light_source {
  <0, 0, 0>            // light's position (translated below)
  color rgb <1, 1, 1>  // light's color
  translate <-30, 30, -30>
}

#declare Exhaust_Color = <0.7, 0.8, 1.0>;

#declare Rocket_Exhaust = difference {
 sphere {
  0, 1
 }
 cylinder {
  -1 * x, 0 * x, 1
 }
 material {
  texture {
   pigment {
    rgbt 1
   }
  }
  interior {
   media {
    emission Exhaust_Color * 5
    samples 10, 10
    density {
     spherical
     poly_wave 2
    }
   }
  }
 }
 hollow
 scale <10, .75, .75>
}

cylinder {0,<-1.8,3,-.75>.6 pigment {color Silver} finish {metallic 2 brilliance
5 reflection .4}}

Rocket_Exhaust

//end of code!

Cheers!

I think it was Kevin Loney in article <3cf94513$1@news.povray.org>

The thread was entitled : A break from my IRTC entry
