My POV-ray tutorial told me that if I wanted the sun created by the
sky_sphere command to emit an apparent shadow through clouds, I'd have to
make a really large sky_sphere with the proper texture,and put the
light_source outside the sky_sphere. How do I do that, since the tutorial
never told me? Here's the programming language below I used to create the
sky_sphere with the sun and clouds, but the clouds do not cast shadows.
#include "colors.inc"
#include "finish.inc"
camera {
location <0,1,-10>
look_at <0,4,0>
angle 80
}
light_source {<0,1e4,10000>White scale 1300}
sphere {
<0,2,0>,1
pigment {color rgb <1,1,1>}
finish {ambient .2 diffuse 0 reflection .6}
}
sky_sphere {
pigment {
gradient y
color_map {
[0,.002 color rgb<1,.2,0>
color rgb<1,.2,0>]
[.002,.2 color rgb<.8,.1,0>
color rgb<.2,.2,.3>]
}
}
scale 2
translate -1
pigment {
bozo
turbulence .65
octaves 6
omega .7
lambda 2
color_map {
[0,.1 color rgb<.5,.5,.5>
color rgb<.75,.75,.75>]
[.1,.5 color rgb<1,1,1>
color rgbt<1,1,1,1>]
[.5,1 color rgbt<1,1,1,1>
color rgbt<1,1,1,1>]
}
scale .1
}
rotate -135*x
}
plane {
y,0
pigment {color Green}
finish {ambient .3 diffuse .7}
}

This is the wrong group for this question. This group is for discussion of
the POV-Ray source code. General questions about using the POV-Ray scene
description language should be asked in either povray.general or
povray.newusers.
