Yeah, I've already tried removing all of the lights and redoing them from scratch but it still does it. If I set the 3D view to wireframe, move a light, rebuild lighting and then switch back to dynamic lighting so I can see the effects that works most of the time.

The fact that it still does it when removing the lights and adding them again leads me to believe that it's a brush issue. Looking at the brushes real close does show some overlaps but that would call for a lot of brush clipping to fix it that way. It does have one real complex brush in it that I'm going to remove and try again.
                                                                 Thanks
