Skew Shaders pour Minecraft 1.20.1, 1.21.1

Subtle instability. Dynamic motion. Zero gameplay impact.

This lightweight post-processing shader adds animated screen distortion, directional skew, and camera-like shake to create a more intense and immersive visual experience. Designed for OptiFine and Iris compatibility, it runs entirely as a fullscreen effect with minimal performance overhead.

✨ Features

Animated Screen Skew A time-varying shear transformation subtly bends the image horizontally and vertically, creating a dynamic sense of movement without becoming distracting.

Micro Camera Shake Procedural jitter introduces tiny camera movements that make the scene feel less static. Scaled by screen resolution to remain consistent across devices.

Dynamic Rotation A gentle rolling motion adds natural instability and prevents the effect from feeling mechanically repetitive.

Scanline-Based Distortion A lightweight horizontal wobble effect simulates slight signal interference and enhances motion intensity during gameplay.

Procedural Noise Texture-free hash noise drives the shake system, ensuring smooth animation with virtually no additional resource usage.

Safe Edge Handling UV clamping prevents artifacting and edge stretching on drivers that struggle with out-of-bounds texture sampling.
