The nastiest RP
This resource pack/shaders are challenges to complete. The shader is designed so that you can play it somewhat, but the image is extremely unpleasant to look at.
You can try to complete Minecraft with it, play minigames, or troll a friend. Whatever you choose.
To enable this effect, go to Settings → Video Settings → Graphics = Fabulous!
