Light Issues
The level shows up normally when lights are off but if I turn them on, or even just one the faces start disapearing for some reason. Normals should be right, I''ve even got the program showing the normals. and the look fine.
do you use glEnable(GL_NORMALIZE). . . i think it invokes a performance hit, but i had to do that, because my normals were not unit length . . .
