Weather FX - Rain VFX, Snow, Fog and Water Shaders for Godot 4

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

Try it first: click Run asset pack above and toggle and stack all 12 over a pixel-art landscape in 11 moods, in your browser.

var rain := WeatherFX.add(self, "rain", {density = 0.8})
WeatherFX.add(self, "fog", {color = Color.LAVENDER}).fade_in(3.0)
WeatherFX.add(self, "water",
    {position = Vector2(0, 520), size = Vector2(1280, 200)})
$Storm.strike()
rain.stop(2.0)

What's inside

Weather that covers the screen and follows the camera: rain (with splashes), snow, fog, lightning, falling leaves or petals, cloud shadows, god rays, heat haze

Water: a lake that reflects your scene with waves and glints, a waterfall with foam and mist, underwater caustics

Time of day: day_night tints the whole scene from dawn through noon and dusk to night, held or cycling

• Colour, strength, speed and wind on every effect, plus sliders of its own: density, drop length, fog height, ray count, wave height, strike frequency...
• Pixel-art mode: set pixel_size on one effect, or WeatherFX.default_pixel_size once for the whole game, and the effects draw in crisp, world-aligned pixels that match your art.
• Layer them: rain over water with lightning, snow at night, fog under god rays.
• Patterns stay put in the world while the camera moves.
• fade_in() and stop() for weather that comes and goes; strike() for lightning on cue.
• Drop a WeatherFX node in a scene and it previews itself in the editor.
• Demo project: a pixel-art landscape in 11 moods, toggle and stack every effect.

Compatibility
