Demonic Possession is a post-processing shader designed for horror-focused Minecraft experiences. It solves the problem of creating a convincing visual representation of possession and reality breakdown without requiring complex command blocks or resource pack editing. The shader introduces animated distortion effects that make the world feel unstable and hostile, ideal for horror maps, ARGs, and analog horror sequences.

The shader features a living spiral distortion that continuously pulls the screen towards a shifting vortex, with intensity increasing over time. Mirror fractures split the view into broken fragments during possession peaks, while random horizontal tears distort sections of the screen to simulate corrupted perception. Natural colors are gradually replaced with a hostile crimson palette, and shadows become deeper and more oppressive.

Living Spiral Distortion - Reality is pulled toward a shifting vortex that intensifies over time, creating a sense of losing control.
Mirror Fractures - The screen breaks into mirrored fragments during possession peaks, making familiar environments feel unfamiliar.
Tearing Reality Artifacts - Random horizontal tears distort screen sections, simulating corrupted perception and unstable vision.
Demonic Color Corruption - Natural colors are drained and replaced with a hostile crimson palette, with darkened shadows.

This shader is intended for use with OptiFine or Iris Shaders on Minecraft Java Edition. It works best with vanilla-like resource packs but may conflict with heavy post-processing shaders. Performance varies; lower-end systems may experience frame rate drops during intense distortion effects. The shader does not alter gameplay mechanics—only the visual presentation. For optimal results, use in controlled horror environments where the gradual corruption effect can be fully appreciated.
