well if your wanting the lighting to stay put, depending on your card, you can hit 7 to use the lights and hardware texturing, Use as many lights as it will suport. With the higher Gcards you can use dmap shadows in your view port also. I had up to 4 spot lights with a crappy really old Nvidea card. Wasn't looking like GI-Joe but looked better than none.

is this something like your talking about ?
