MotionSickness

Motion Sickness

The shader nobody asked for. Motion Sickness turns Minecraft into a boat ride in a storm: the ground rolls in waves, the horizon bends into a bowl and then a planet, distant terrain slowly spins around you, and your camera sways, breathes and sees double. Perfect for pranking a friend’s PC, or for challenge videos (“Can I beat Minecraft with the Motion Sickness shader?”).

World Warping

| Effect | Default | What it does |
|—|—|—|
| Ground Waves | On | Terrain heaves up and down like an ocean swell (even a bit under your feet) |
| World Spin | On | Far-away terrain slowly twists around you |
| Bendy Horizon | On | The world curves up into a bowl, then down into a tiny planet, over and over |

Screen Effects

| Effect | Default | What it does |
|—|—|—|
| Camera Roll | On | The screen tilts and rolls side to side |
| Breathing FOV | On | The view zooms in and out like it’s breathing |
| Jelly Screen | On | Wobbly, wavy distortion |
| Double Vision | On | A ghost copy of the world slides around |
| RGB Split | Off | Red, green and blue drift apart |
| Color Drift | Off | Colors slowly shift hue |
| Drunk Stumble | Off | Every few seconds the camera lurches in a random direction |

Settings

• Nausea Level: 0.25 (mild prank) up to 3.0 (unplayable)

Performance

Very cheap: no shadow map and a single final pass. Runs on basically anything.

⚠️ Warning

This shader is designed to cause motion sickness and dizziness. Stop if you feel unwell. Colors shift slowly and nothing strobes, but if you are sensitive to motion or flashing visuals, use a low Nausea Level or skip it.

Compatibility

Minecraft Java Edition with Iris (Fabric / Quilt / NeoForge) or OptiFine.
