Hi,

I am new to povray and have been trying to create a sphere with a cloud
map on it that casts shadows as clouds normally would.  I have got the
shadows cast ok but I can not see the cloouds or sky.
I am using the following pattern.  I sort of know whats going wrong but
can't see how to solve it.  If I put a light source below the sphere
then I can see the clouds fine but when the souce is above I get the
nice shadows but no sky.  Can anyone point out what i am doing wrong??

TIA
Ross
