After playing around with the lighting to a house I'm making, I seem to have ruined my draw distance. I changed everything back to the way it was before I made these changes, but it doesn't seem to help at all. Near is set to 0, Far is set to 9000 and Pow is set to 1 if that helps. Here's a screenshot too: http://imageshack.us/a/img690/5581/5y02.jpg

Does anyone know how to fix this?
