I've been trying to use the following pov-ray code in moray without much
success. Can this be used in moray or is it just megapov specific?

Thanks,
dcc


difference{ sphere{ <0,0,0>, 10010 } sphere{ <0,0,0>, 10000 } hollow
translate <-40,-10000+90,0>
//box{ <-100000,40,-100000>, <100000,50,100000> hollow
  pigment{ color rgbf <1,1,1,1> }
  interior{ media{
      method 3  intervals 1  samples 20,1000  aa_level 6
      emission <1,1,1>
      scattering{ 1, color rgb <1,1,1> }
      density{ wrinkles
        density_map{
          [0 color rgb <0,0,0>]
          [0.6 color rgb <0,0,0>]
          [1 color rgb <1,1,1>]
        }
        scale 150
      }
  } }
}

This is specific to MegaPov. You can tell because it uses sampling
method 3 and aa_level 6. If you remove these and increase the
intervals level you might get similar results but there is no
gaurantee that you will get a perfect match and it is likely
that the rendering time will be much longer.

That's what I thought.

Thanks anyway.

To use this script with moray, you must use it as an include and it 
will work ok (if you render the scene with megapov of course).
