Darken Shaders

[gondracorn]

Is there a shader where you can darken/brighten the screen or something? (Without messing with the Monitor's settings)? Or certain elements for all/a game?

You can use my shader(link in the signature), edit the fsh file with any text editor, all it's options are at the very top and hopefuly described well enough, so just disable all unwanted effects and enable shadeboost and/or gamma to mess with the colors however you want. Some other effects there also aim at messing the colors in a slightly more complex ways. Note that post process shaders are re-compiled whenever you resize window, switch fullscreen or even pause/restore the game, so it's all easy to tweak while running a game.

Post process shaders will apply for whole screen, so if you want to affect only some specific elements, you will have to invent some way to differ those things from everything else which might be hopeless for detecting complex, very specific shapes, not impossible, just stupidly heavy and useless, it's literally cheaper to produce beautiful 3D scenes without any texture lookup(via procedural generation;p). Althrough simpler color detection is cheap and very doable, most common effects do just that and if you ever had any programming experience learning GLSL is really nothing special.

Replacing textures could also work since noone stops you from using lighter/darker/completely different textures.
