Hi Ken,

this is the resulting image for the candle code, a screenshot of
Moray's Material Editor with the texture and the material in Moray's
Material Library format. 

This is the verbatim copy of the material that Moray exported:

#declare FlameTexture = 
   material  // FlameTexture
   {   
      texture
      {      
         pigment
         {
            color rgbt <1.0, 1.0, 1.0, 1.0>
         }
      }   
      interior
      {
         media
         {
            intervals 20
            confidence 0.999
            variance 1.0/100.0
            emission rgb <1.0, 1.0, 1.0>
            scattering
            {
               1 ,  rgb <0.01, 0.01, 0.01> // isotropic scattering
            }
            density
            {
               spherical
               color_map
               {
                  [ 0.0     rgbft <0.0, 0.0, 0.0, 0.0, 0.0> ]
                  [ 1.0     rgbft <5.0, 3.0, 0.0, 0.0, 0.0> ]
               }
               turbulence 0.4
               lambda 1.0
               cubic_wave
               scale  <0.8, 1.0, 0.8>
            }
            density
            {
               gradient y
               color_map
               {
                  [ 0.0     rgbft <0.0, 0.0, 0.0, 0.0, 0.0> ]
                  [ 1.0     rgbft <1.0, 1.0, 1.0, 0.0, 0.0> ]
               }
               cubic_wave
               translate 1.0 * y
            }
            density
            {
               gradient y
               color_map
               {
                  [ 0.0     rgbft <0.0, 0.0, 0.0, 0.0, 0.0> ]
                  [ 1.0     rgbft <1.0, 1.0, 1.0, 0.0, 0.0> ]
               }
               poly_wave 0.5
            }
         }
      }
   }

Granted, it doesn't parse as fast as your obfuscated POV code.....
relax, just kidding <g> (about the obfuscated).

I did have to look at the POV-Ray docs to figure out what your code
was doing in two places<G>.

And you did help me to discover one bug related to reloading a texture
from file with out-of-range values. Thanks!
