Nope, here's a simple scene:

#include "colors.inc"
background{Black}

camera {
  angle 20
  location<0,2,-10>*1
  look_at<0,0,0>
}
light_source { <10, 20, -10> color White }

 sphere
 { 0,1 pigment { rgbt 1 } hollow
   interior
   { media
     { emission 1
       density
       { spherical density_map
         { [0 rgb 0]
           [0.4 rgb <1,0,0>]
           [0.8 rgb <1,1,0>]
           [1 rgb 1]
         }
       }
     }
  }
 }

try using +fn8 +ua, first render as I posted it and then coment the second line
and see what happens :(
