Thanks Pokey. I apreciate you guide for the cool effect you've achieved there. "It will be great if CL tweaks the atmosphere to allow us to choose which light to apply atmosphere to... I would like to be able to use an infinite light and then have a spot to enhance an area, such as light coming from a window, through clouds, smoke, etc" Dave, I totally agree. It will offer so many interesting variables that way from particualar light sources. Another example would be a light beacon from a light house while in the same picture the moon is glowing. The programmers at CL are probably saying "okay Dave, Lapis, shut up already"(lol). shut up all ready
