3 animated 2D weather effects for Godot 4, free, one line of code each. Every effect is a single shader on a single node: no textures, no particle setup, sharp at any size.

var rain := WeatherFX.add(self, "rain", {density = 0.8})
WeatherFX.add(self, "fog", {color = Color.LAVENDER}).fade_in(3.0)
rain.stop(2.0)

Weather FX has all 12: lightning, a lake that reflects your scene, a waterfall, falling leaves, cloud shadows, god rays, heat haze, underwater caustics and a day-night cycle on top of these three. Same node, same code: install it over this one.

What's inside

• rain, with splashes where it meets the ground, snow and fog: they cover the screen and follow the camera, while the patterns stay put in the world.
• Colour, strength, speed and wind on every effect, plus density, drop length, flake size, fog height and more.
• Pixel-art mode: WeatherFX.default_pixel_size = 4 and the effects draw in crisp pixels that match your art.
• fade_in() and stop() for weather that comes and goes.
• Drop a WeatherFX node in a scene and it previews itself in the editor.

Compatibility

• Godot 4.3 to 4.7, tested on both ends.
• Forward+, Mobile and Compatibility renderers: desktop, mobile and web.
• GDScript only: no C#, no GDExtension.
