How do I turn on Gray Wobbly World Shaders?
Open Options, then Video Settings, then Shader Packs. Select Gray Wobbly World Shaders in the list and click Done or Apply. Once the world reloads it should turn gray and start warping.
Do I need Iris or OptiFine for this to work?
Yes. This is a shader pack, so it needs a shader loader like Iris or OptiFine. Without one there is no Shader Packs menu and the pack can't be selected.
I don't see the pack in my Shader Packs list, what's wrong?
Make sure the pack file sits directly in your shaderpacks folder and isn't buried inside an extra folder. Then reopen the Shader Packs screen so the list refreshes.
How do I turn it off and get my colors back?
Go back to Video Settings, then Shader Packs, and select OFF (or no shader) instead of Gray Wobbly World Shaders. If you use Iris, check your Controls menu for its toggle-shaders keybind, which turns shaders on and off without opening menus.
If I put this on a server, will everyone see the gray wobbly screen?
No. Shaders run only on your own game, so only the player who has it enabled sees the effect. To prank a friend, it has to be turned on in their game, not on the server.
Does the wobble actually move blocks or mobs, or is it just visual?
It's purely visual. Blocks, mobs and hitboxes stay exactly where they normally are, and only the image on your screen bends. That's why aiming and building feel off even though nothing in the world has changed.
How do I tell mobs and ores apart when everything is gray?
Rely on shapes, textures and sounds instead of color. Creeper hisses, zombie groans and the distinct patterns on ore blocks still give them away. Brightness differences also help separate things like water, lava and stone.
The wobbling is making me feel sick, what should I do?
Turn the shader off right away through the Shader Packs menu and take a break. The constant warping is the whole point of the pack, so if motion bothers you, play in short sessions or save it for quick pranks.
Can I use this together with another shader pack?
No. Iris and OptiFine only run one shader pack at a time. Picking Gray Wobbly World Shaders replaces whatever pack you had active, and switching back means selecting your old pack again.
Will this shader lag my game?
It's a screen-wide gray filter and warp effect rather than a realistic lighting pack, so it usually runs lighter than heavy shaders. It still uses your graphics card, so lowering render distance helps if your FPS drops.
