Hello. I'm trying photons for the first time. I like the effects shown in
the attached image, but is there a way to get rid of the shadow of the disc
without getting rid of the photons? i tried shadowless on the light source,
and no_shadows on the disc itself, but both resulted in no photon
calculations.

the shadow itself doesn't seem to be a result of photons. here is the
relevant (i think) code. I also tried making the glass texture have color
rgbft<1, 1, 1, 1, 1> and that didn't rid the scene of the shadow. originally
exported from moray, so the coordinate system might be different than
default pov.

thanks,
ross.



#declare Glass =
   material  // Glass


      texture


         pigment
         {
            color rgbf <1.0, 1.0, 1.0, 1.0>
         }
         finish
         {
            ambient 0.0
            diffuse 0.0
            specular 1.0


         }
      }
      interior
      {
         ior 1.5
      }
   }


disc {
  <0, 0, 0>
  1*z,
  1
  material {
    Glass
  }
  normal {
    wrinkles 1
  }
  photons{
    target
    reflection off
    refraction on
  }
  translate 1*z
}
