Retro Screen FX - CRT, VHS, Game Boy and 1-bit for Godot 4

Make any Godot 4 game look like it runs on a CRT, a VHS tape, a Game Boy or a 1-bit Mac. One node over your 2D or 3D game, 12 presets, and every parameter a slider.

var retro := RetroScreen.new()
retro.preset = RetroScreen.Preset.CRT
add_child(retro)

Presets

Features

• 24 parameters in groups: pixels, colour, CRT, VHS. Mix them freely: a Game Boy palette on a curved CRT is one line.
• Palettes are N x 1 images: drop in any Lospec palette of up to 64 colours.
• Ordered dithering locked to the retro pixel grid: crisp patterns, no noise shimmer.
• Works over 3D and 2D. UI on a higher layer stays sharp.
• The shader also runs on any smaller ColorRect: a retro TV inside your game, a minimap.
• split parameter for before/after screenshots.
• Demo project: a 3D and a 2D scene with a button for every preset.

Compatibility

• Godot 4.3 to 4.7, tested on both ends.
• Forward+, Mobile and Compatibility renderers: desktop, mobile and web.
• One .gdshader and one GDScript file. No plugins to enable, no C#, no GDExtension.

Install

Copy addons/retro_screen/ into your project, then add a RetroScreen node. Open demo/demo.tscn to try every preset.

License

Use in unlimited commercial and non-commercial games. No attribution required. Don't resell or redistribute the shader itself as an asset.

Made with AI assistance (code, text, demo art), tested in Godot 4.3 and 4.7 on every renderer.
