I looked over some lightmapping techniques in the code archives and they were way beyond me. The idea was to create a lightmap of the scene, render the scene with the lightmap, move characters, create a new lightmap, then render the scene again.

In reality this theory is similiar to ShadowMapping, but shadowmapping is alot simpler.
Load Scene
Create Shadowmap image from Light Perspective
Render scene in all shadow
Compare pixels of scene with image to see whats visible
Render scene again but dont update any "blocked" pixels, sot they stay shadowed from the shadow render.

errr something like that anyways. This seems to be the method Im looking for but as of right now Im still at the Blob Shadow stage, lol.
