the light source on the clouds is white .... it fired up the scattering 
media the best. I used emission and absorption to get the color variations. 
the macro I wrote accepts enough parameters so I can tweek each clouds 
appearance .... and yes the cloud light (in the light_group) is close to the 
clouds, and low on horizon, in relationship to the main scene light. the 
clouds are all placed at the same elevation (y dir) ..... the left side 
clouds are in the shadow of the right side clouds.
