I was wondering if there was a way to alter the light/shadow a material receives. I was looking through screenshots of “The Wolf among us” and noticed a very distinctive art feature was the fact that outlines in objects were black when the object was lit, and became brightly colored when hit by shadow.
Is there a way for materials to check how much light is hitting a certain pixel or something? Ideally I’d like to pass my material instances a black and white texture, and have the white parts of that texture be black in the light and colored/transparent in the dark.
