pre-rendered? that draws a blank.

it seems the right way, is to do the moon as seen here,
only with a cloud atmosphere between it and camera.

need more info on:
sky (transparent)
pre-rendered




I was able to remember vicky's hair and did this.

#declare p_map1=pigment {image_map{jpeg "moon" interpolate 2 transmit all 0
filter all 0} }
#declare p_map2=pigment {image_map{png "moontr" interpolate 2 }}

#declare halfmoon = texture{ pigment{ p_map1} }

#declare half_moon =  material {
texture { pigment_pattern{ p_map2}
texture_map { [ 0 pigment{Clear} ]
             [  1 halfmoon       ]
           }
     }
