[Dev-C++] OpenGL Lighting Question

[<ste...@ge...>]

Hi all!

I'm having serious problems with my lighting in OpenGL. I've read some =
tutorials on the subject at Nehe's Site.
When I make a room out of 4 walls (4x1) and floor and ceeling (4x4), the =
light won't lit up the floor and ceeling properly.

Where can I learn more about light in OpenGL?

Thanks!
