Procedural TV Noise & Scanlines Shader

Procedural TV Noise & Scanlines Shader is a customizable URP Shader Graph effect that recreates classic analog television static, noise, and scanlines in real time. Designed for retro screens, glitch effects, surveillance monitors, sci-fi interfaces, horror atmospheres, and stylized post-processing, it generates fully procedural TV static without textures, keeping performance high and setup simple.

The shader includes adjustable parameters for noise intensity, scanline density, animation speed, flicker behavior, and distortion, allowing developers to quickly create convincing CRT, VHS, broadcast interference, and damaged screen effects directly inside Unity materials.

Perfect for games, cinematic scenes, UI screens, terminals, and in-world displays, this shader works seamlessly with the Universal Render Pipeline (URP) and can be applied to meshes, screens, or full-screen effects to instantly add retro television aesthetics to your project.
