What i want to achieve is to make the pitch-black shadows disappear. If these shadows are there due to the stencil shadows(if that's what you've said), i will have to try and get shadow maps to work on the world... Although i don't have so much hope. Thanks for your reply and for the code you've linked. If there is a way to remove the pitch-black areas (and make them simply dark) without needing to re-write the system, please tell me
Also, what are arb shaders? I don't have a good insight of this in general.
Edit: I've found no draw_exp.cpp in the Doom 3 SDK. I'm either using an older version of the SDK, or you were referring to your code, which does have this file.
