Enabling and Toggling Cursed Metamorphopsia Shaders in Game

Activating the Distortion Effect

Once Cursed Metamorphopsia Shaders is placed in your shaderpacks folder alongside a compatible shader loader like Iris or OptiFine, you can turn on the wavy visuals directly from the pause menu without restarting your game.

1. Load into your world or pause the game and click Options.

2. Select Video Settings, then open the Shader Packs (or Shaders) menu.

3. Click Cursed Metamorphopsia Shaders in the list of available packs.

4. Click Done or Apply and return to the game.

Straight lines across blocks, terrain edges, and held items will immediately appear bent and wavy, creating the intended unsettling atmosphere.

Temporarily Disabling the Shader

Because the shader alters how normal block shapes look, you may occasionally want to double-check a build's alignment or take a break from the visual distortion.

• Using Iris: Press your configured shader toggle keybind during gameplay to switch the wavy effect off and on instantly.
• Using the Menu: Return to Options > Video Settings > Shaders and select Off (or (internal) in OptiFine) to restore standard straight-edged rendering.
