Cripe - Visual Corruption and Display Degradation Shader

Cripe is a lightweight post-processing shader designed around visual corruption effects rather than realistic lighting. Instead of altering Minecraft's world rendering pipeline, it applies a series of screen-space distortions that make the image appear unstable, degraded, and intermittently damaged. The shader combines chromatic separation, block-based corruption artifacts, temporal ghosting, scanline interference, and subtle film-like degradation to create an unsettling visual atmosphere while remaining technically simple and inexpensive to render. This approach solves the problem of adding horror or glitch themes to Minecraft without requiring high-end hardware or complex resource packs.

This shader is best suited for players creating custom maps, horror adventure worlds, or anyone wanting a cursed or potato-friendly visual style that feels broken rather than enhanced. It fits well with vanilla-like expectations because it does not overhaul lighting or shadows; it only corrupts the final image. Use Cripe for thematic effect in abandoned dimension builds, decay-themed servers, or as a visual storytelling tool where instability is part of the narrative.

• Screen-Space Corruption Distortion – Divides the image into a coarse grid where random regions become offset independently, mimicking corrupted video memory or damaged rendering.
• Chromatic Separation – Splits color channels with slight offsets to create a glitchy, misregistered look.
• Block-Based Artifacts – Introduces rectangular patches of corrupted pixels that appear and fade over time using pseudo-random patterns.
• Temporal Ghosting – Adds a faint trailing effect to moving objects, suggesting incomplete frame reconstruction.
• Scanline Interference – Overlays subtle horizontal lines and noise reminiscent of old CRT displays or signal degradation.

Limitations and requirements: Cripe is a potato-friendly shader that runs on most hardware, even integrated GPUs. It does not modify lighting, shadows, reflections, or water; players seeking visual realism should look elsewhere. The shader may conflict with certain post-processing mods or OptiFine settings. For best results, disable other shaders and use a recent version of Iris or OptiFine. No special memory or GPU drivers are needed.
