Hello Everyone, Sorry for all the newbie questions, but I AM really learning from all this info.... I am now able to make a gray square things with holes in them... I'm very proud (Just kiddin'around ;) .. I'll actually have another image to post this weekend :) I've been playin' with Volumetric selections for atmospheres and materials, but I don't get it... Why and (maybe) when would I want to use Volumetric selections instead of the regular materials? Thanks very much, John
