Just use une single box twice as high and put the two media in it, translated as
needed. When you have more than one media in a container, they add toggether.
Your container and media become:
box{0,1 scale 2*z
hollow
pigment{ color rgbt 1 }
interior{
media{
emission 1
density{
density_file df3 "00001325.df3"
interpolate 0
translate z
}
}
media{
emission 1
density{
density_file df3 "00001325.df3"
interpolate 0
}
}
}
translate <4, 4, 3>
}

You know you've been raytracing too long when you resign the fact that printing
uses CMYK instead of RGB to one of those tests God gave to Job; otherwise life
would be too painful to go on.
