I just noticed that regardless of any point light sources, in any given room, the walls on the eastern side always appear darker, as well as the ceiling. What is going on in the engine to cause this? Is there some sort of light source in the skybox area that is causing that? I do not have any skybox. Any workarounds?
Ahh I see, thanks. Is it sort of like how the original Doom engine had "fake contrast" depending on face orientation? I can live with it like that.
