--- Comment #3 from Matheus matheus.venturini@acad.ufsm.br --- This also happens in Penumbra: Black Plague, but NOT in Amnesia: The Dark Descent, which was made by the same developers and uses an altered version of the engine used in the Penumbra games. In fact, Amnesia doesn't have a "Post Effects" setting at all.
Just like with Overture, lighting effects do not work in Black Plague.
