The first one doesn''t really help much unless you already know enough about lightmaps ;( The second one is only a siggraph slideshow that demonstrates the basic technique involved. The third one is the best bet. There is a demo called ''Fake Dynamic Lights'' that might help.

Lightmapping is actually multitexturing, where the normal texture is applied first, and then the lightmap is applied on it, in effect multiplying the two textures together (blending)... but how is that done ?!?

Anyway, I''m looking for a lightmap tutorial myself. I just wrote a little prog that exports Quake 2 level data into my own file format. I can load the level w/ textures and walk through it... but it sure would be nice to have the lightmaps as well!

If anyone knows of any, PLEASE post a link !!!
