Hmm.. already tried increasing the intervals *and* method 1... all it seemed
to do was slow down the rendering time even further.

I am indeed using POV-Ray 3.5 beta 12. I guess I should post a code example
to show what I'm doing right now...

#declare Bussard_Collector_Dome_Interior = interior {
     ior 1
     fade_distance 1
     fade_power 1001
     fade_color rgb <0.9,0.9,0.9>
     media {
          intervals 10
          samples 3,10
          confidence 0.99
          variance 0.1/128
          ratio 1
          scattering {2,   rgb<0.45,0.3,0.25>}
          method 2
          jitter 0
          density {spherical  scale 7.5}    // radius of dome is 7.5
     }
}

thanks...
