Hi All

Help this is urgent

I need a flame that will show up clearly against a lightish background problem is I
don't have time to experiment as I have a very
tight deadline to meet.

I know about using emitting media and absorption but my first attempts gave me
transparent or blue flames.

Any snippets of code that will get me moving in the right direction would be very
gratefully received.

Absorbtion and emission colour shoud be opposite.

---%<------%<---
#version 3.5;
global_settings {assumed_gamma 1.0}
camera {
  location  <0.0, 0.0, -3.0>
  look_at   <0.0, 0.0,  0.0>
}
light_source {
  <500,500, -500>
  rgb <1, 1, 1> 
}
plane {
  -z,0
  pigment {checker color rgb 1 color rgb 0}
}
sphere {
  0.0, 1
  hollow
  texture {
    pigment{rgbt 1}
    finish {ambient 0 diffuse 0}
  }
  interior {
    media {
      method 3
      intervals 2
      samples 1,1 
      emission rgb <1,1,0>
      absorption rgb <0,0,1>
      density {rgb 1}
    }
  }

Thanks Ingo

I must stop thinking about colour in paint terms and start thinking about it
scientifically.

I don't remember where I got it, but I found some pov code somewhere on my
hd. Check the povray.text.scene-files for the code.
