Super Secret Settings

A lightweight 1.17-1.20 Fabric Mod which adds the Super Secret Settings feature removed in 1.9. It works almost exactly like it did in the older versions. 

The options menu.

A new button can be found in the Options Menu. When pressed it will play a random sound like in 1.8 and if you are playing in a world or on a server a shader will be applied.

The shaders are always applied in the same order which is: Notch, FXAA, Art, Bumby, Blobs2, Pencil, Color convolve, Deconverge, Flip, Invert, NTSC, Outline, Phosphor, Scan pincushion, Sobel, Bits, Desaturate, Green, Blur, Wobble, Blobs, Antialias, Creeper and Spider. More information can be found on the Minecraft Wiki.

Super Secret Settings can be turned off by shuffling through all shaders or setting keybinds in the controls menu.

You can also access a new menu screen by shift-clicking the new button. Here you can go back, forward or turn the shaders off.

Shader N. 3: Art

To use this mod you need the Fabric API installed.

!! These settings can cause performance issues for slower computers. !! Some shaders are not suitable for people sensitive to flashing colours. !!

This mod is entirely cosmetic and does not provide advantages in-game. Have fun!
