Filtr

Post-processing presets for Godot 4. Add a FiltrNode, pick a look, done.

Comes with a preset browser in the editor dock. VHS, PS1, noir, bloom, chromatic aberration and more — swap between them without touching a shader.

Zone system lets you trigger visual changes when a player enters an area. No code needed, just place the node and set the preset.
