Hello,

sorry for that question but somtimes I'm too stupid to find the correct
answer on my own. In original state my sky consists of:

sky_sphere {
     pigment{P_Cloud4}
     scale 2
}

In my animation I want to blend this sky out so that I only have a "White"
sky. I tried already a lot of combinations with "transmit clock" but I only
managed to get an black sky. I also tried this in combination with a white
pigment. Can anybody help me, please?

Regards
Wolfgang

You can add a layer that have a transmit going from 0 to 1. The pigment will looks
like:
pigment{rgbt <1,1,1,1-clock>}
Will go from totaly transparent, showing previous pigment in the list, to totaly
white.

What Alain said, but also adding finish{ambient clock} or finish{ambient 1}
in a texture statement helps, or you'll be fading to whatever amount of
light you've got available.  Try different settings with this and +k.5 for
example :
Charles C

#include "colors.inc"
#include "skies.inc"

camera {location <0,.1,-4> direction 1.5 * z look_at <0,0,0>}
light_source{<-30,30,-30> color rgb 1 }

#declare FadeToWhiteTexture =
        texture{
                pigment { rgbt <1,1,1,1-clock> }
                finish { ambient clock }
        }

sphere{ <0,0,0> 1 texture{FadeToWhiteTexture} scale 5000  }

sky_sphere{ pigment{P_Cloud4} scale 2 }

sphere{0, 1 finish{reflection 1}  }
