Me again!

My terrain looks kind of flat, and was thinking of baking the shadows, and the applying a pass to make the scene look shadowed.

My terrain is pretty big and I have to use different textures to make the landscape look not so pixilated, and in most cases tiling textures. So I though that applying a 512x512 shadow map to the whole terrain will help on adding depth to the scene.

Any suggestions?

Thanks again...

Shadow maps (aka light maps) require that you create them in the first place, and then create a method for producing the combined textures. I got lost on learning this, but usually it requires a processing phase on your scene model which produces the light maps, usually with the help of a radiosity algorithm to calculate them.

What's wrong with using OpenGL's own lighting? Light maps give the illusion of complex lighting and are necessary for self-shadowing if you don't want to write a dynamic self-shadowing renderer (and I'm sure you don't), but will self-shadowing be essential to your game? Of course light maps are much better looking that vertex lighting, and faster to render, at least indoors. On terrain, it is probably a whole other ballgame.
