Hi, I'm new to PovRay and raytracing, since I downloaded it I love it.

I'm trying to make a outdoor scene with a "flame" (sphere with some media 
in it). Without using fog the scene looks ok, but when using fog, the 
sphere which contains the media becomes visible. Changing the fog distance 
helps, but ruins the rest of the scene.

The sphere is declared like this:

#declare flame = sphere{
 <0,0,0>,2
 pigment { color transmit 1.0 }
 hollow
 interior {
  media {
   absorption 50 
   emission 28 
   scattering {1, 1}
   density {fire} 
   translate wind*clock
   }
  }
 }

I also tried 

pigment { rgbf <1,1,1,1> }

but nothing seems to work. Is there a way to make the sphere invisible so 
that even the fog continues inside it, or at least not "condense" around 
it's boundarys? Any suggestions would be welcome.

Cheers,
Louis
