Texture Lighting

[Neziroth]

I'm having a small problem with the whole idea of texture lighting. I've had experience with brush editors and such before, (worldcraft). Even with my past experience I can't figure out the anything about getting textures to emit light. I know it has something to do with Shaders, which I also don't understand...

 

Can someone explain the following to me... in detail:

-Texture Lighting how-to

-Shaders, how they work, what they do, where to find them

 

Thanks,

Nez
