Render times are not my concern when it comes to rendering. I'd use the sphere in open space(Off the ground, or without the ground plane,) actually. I'm going to need to test the would'nt make a differance part for myself. I've heard that one before. With twice as much light of course there is going to be a huge differance, as reflected in the render times... I really just do'nt want to align this, and am hoping someone has already done this... = )
