Yep. It washed out all the colors towards a dull brown. Even the clouds
were tinted brown. I can't get the hang of the new radiosity features yet.

They are a simple macro: two cones and a little random turbulence on the
second cone. I'd like to make them a bit more detailed, but there's a
lot of them and I'm worried about memory consumption (Granted, I just
got a RAM boost so I shouldn't have as many problems now)

I used assumed gamma 1.2 for that render. I forgot to set it back to
1.0. It didn't make any difference on my screen.

Both the mountain peak and the range were the result of an experiment. I
was trying to develop a more realistic background for the IRTC animation
entry I am working on and a happy accident led me to develop this scene,
which I've had in my head for some time. I'd like to say it was
completely done in POV-Ray, but the ship body is an intersection of
three height-fields.

Here is the mountain code:
#declare Peak =
height_field {
      function 400,400 {
         pigment {
            boxed scale 0.45 translate <0.5,0.5,0> turbulence 0.2
octaves 7 lambda 2.1
            poly_wave 2.5 } }
      //water_level 0.001
      translate <-0.5,0,-0.5>
      pigment { slope { <-3,-10,0> 0 0.5 } 
                color_map { [0 Tan ] [0.5 Brown ] [0.51 White*2 ] [1.0
White*2] }}
      rotate 30*y
      scale <3,1.5,3>*40
      translate <-50,-1.001,100>
   }

#declare MountainRange =
height_field {
      function 600,600 {
         pigment {
            cylindrical scale 0.40 translate <0.5,0.5,0> turbulence 0.3
octaves 7 lambda 2.1
            poly_wave 2.0 } }
      //water_level 0.001
      translate <-0.5,0,-0.5>
      pigment { slope { <1,-10,0> 0 0.5 } 
                color_map { [0 Tan ] [0.5 Brown ] [0.5 White*2 ] [1.0
White*2] }}
      rotate 90*y
      scale <-8,1.2,3>*40
      translate <00,-1.001,110>
   }

After plugging the function into a height field I went all out and also
used slope patterns for the first time.
