One of the main uses for Gray Wobbly World Shaders is pranking a friend. When they load their world, the color is gone and the screen warps every time they walk. Only do this on a computer you are allowed to use, with someone who will laugh about it afterward.
Setting Up the Prank
1. On your friend's Minecraft, make sure a shader loader such as Iris or OptiFine is installed. Shader packs need one to work.
2. Open Options > Video Settings > Shader Packs, then click Open Shader Pack Folder.
3. Place the Gray Wobbly World Shaders file in that folder.
4. Back in the menu, select the pack and apply it.
5. Close the menus so the title screen looks normal.
The Reveal and the Fix
When your friend loads their world, everything turns black, white and gray. The moment they start walking, the screen begins to bend. Building and fighting feel strange because the view keeps moving.
Do not leave them stuck. Once the joke has landed, show them how to undo it:
1. Open Options > Video Settings > Shader Packs.
2. Pick another pack, or choose the option for no shaders.
3. Apply the change. Their colors and steady view come back right away.
If they want to keep it as a challenge, leave it on. See the survival challenge guide for tips.
