Personally, I would change the cloud media to the following (in
particular making them white; colour differences should come from the
light and/or environment) and increase samples a bit to reduce artefacts:
box {
<-1,-0.5,-1>,<1,1,1>
pigment {rgbt 1}
hollow
interior {
media {
samples 10
emission <0.9, 0.9, 1>*0.1
absorption <1.0, 1.0, 1.0>*2
scattering {1, <1, 1, 1>*1 extinction 1.0 }
density {
gradient <1, 0.25, 0.5> // controls the cloud formation
turbulence 0.5
frequency 5
color_map {
[0.0 rgb 0.0]//border
[0.5 rgb 0.1]
[1.0 rgb 1.0]//center
}
}
}
}
translate <0, 1, 0>
scale <5, 1.5, 5>
}
