Free Godot 4.2 Shader: Multicolor Dithering for 2D, 3D and Post-Processing (Donitzo)

Overview

Donitzo shares a set of multicolored dithering shaders for Godot 4. The shaders replace the colors of 2D nodes, 3D nodes or the entire screen in the case of postprocessing with a pre-planned dithering pattern taken from a dither palette image, giving the scene an old-school retro look.

Palette colors are chosen with algorithms derived from Joel Yliluoma, and the demo project in the src folder can be imported into Godot 4 to test the shaders. The palette generator script is MIT licensed, all other files are CC0, and the repository is a free download from GitHub.
