Lighting

I have a few maps with caves/indoor structure and ofcorse its dark. Is it possible to just add light to indoor structures without adding single hanging lights. I just want to know basicly how would i light the whole indoor area?

I was wondering if i would have to add planes in max and add a material to them or something??

That's an option, then use some light emitting shader. You could also check the 'affects interiors' checkbox under radiosity in your skytag.

I think someone posted a little tut on this a while back, not sure if it was at GBX or here, but you can indeed use invisible planes that emit like to help light your map.

What i did was extrude some planes in and used a light shader on the outsides, it works awsome. Thanks guys.
