enabling lighting makes ugly
I have a proble with no idea where it comes from. I enabled lightin in OpenGL and it messed my graphics.
Look at the screenshot below.
http://www.geocities.com/stefankjb/ogl/lerror.html
I don''t know if it has something to do with trianglesize, because car seems to be ok but track is ugly. It''d be strange still because lighting disabled everything is ok.
Help me anyone who knows what caused the mess.
Here''s how I set up material and light:
More informaion:
Ugly graphics happens only in screen edges. Triangles that are totally visible seems to be ok.
I use vertex arrays for rendering.

i dont see anything wrong with that picture with the lighting. though the texture coordinates seem very screwed up.
can u show a ''good'' screenshot alongside a ''bad'' screenshot

Sorry if I didn''t explain my problem good enough. Lighting is not the actual problem. It works well. But when I enable lighting the all triangles that are clipped by screen edges seems go messy.
I updated the page and added also good picture there.
