moriador: Ahh cool. My main problem is that whenever i try to use the sky dome, the sky material is either too small, or i have to drastically reduce the focal length of my main camera, otherwise the sky will look too blurry. Is there a particular sky map either HDR or equirectangular that you recommend i use for my domes? And is there a way around to having to reduce my focal length so low?

basicwiz: Will IDL still work for indoor scenes that are completely inclosed? Or do i have to open one side? And do i still have to use a dome for indoor scenes? And what does setting the lights to inverse square falloff do? Sorry for all these questions. I'm still a bit new to this, and trying to learn as much as i can about lighting.
