But I in fact have seen indoor scenes with credible outdoor illumination 
  many times since I first entered this group back in 2000! How do those 
PoV geeks that? Perhaps an ultra-bright sun, and thus correspondingly 
very dark textures on all outside surfaces to get a "realistic" 
brightness of surfaces? Perhaps I should try a sun with a color of, lets 
say, rgb 10?

See you in Khyberspace!
