Easy Weather | Volumetric Clouds & Day cycle

Easy Weather gives your URP scene a living sky in minutes: a full day/night cycle, layered clouds, volumetric fog and a weather system that runs itself - and every part of it is yours to tune from one place.

Designed to work equally well both stylized, hand-crafted visuals or high-quality realistic environments, Easy Weather gives you the tools to create anything from vibrant, colorful worlds to atmospheric, cinematic scenes.

Drop the prefab into a scene, open the Quick Start window, and it checks and fixes your project setup for you. From there, everything is driven by the clock: the sun and moon rise and set, sky colours follow 24-hour gradients you paint, fog and clouds react to the time of day, and weather presets blend in and out on their own schedule.

Sky and time of day

Day/night cycle with sunrise, sunset, day and night events and a day counter
Sun and moon lights that hand over automatically, with colour, intensity, shadow and ambient curves across the day
Sun disc with horizon boost and cloud dimming, so it burns at noon, glows through the haze at sunset and hides behind a storm
Stars, a galaxy band and an aurora for the night
Flexible colour and lighting controls suitable for both stylized art direction and high-fidelity environments
Clouds

A 2D cloud layer on the sky dome, a distant horizon layer, and generated 3D cloud clusters you can fly through
Coverage, density, wind and lighting that weather can animate; a Solid Core control for dense cumulus
Adjustable cloud lighting and density for everything from soft, stylized skies to dramatic, realistic storm formations
Fog

Screen-space volumetric fog with height falloff, noise, soft silhouettes and a horizon band
Colour that follows the sun by day and the sky at night, or a gradient you paint
Water-aware: waves cut the fog correctly, and a low sun still shows through it
Fine control over fog colour, density and atmosphere for both stylized scenes and cinematic, high-quality visuals
Weather

Rain, light rain, snow and thunderstorms included as presets; make your own as assets
Automatic daily scheduling with probabilities, time windows and durations - or start any weather from a single line of code
Presets override sky colours, clouds, fog, fog distance, stars and a post-processing Volume profile, all cross-faded over the transition
Weather audio (rain, wind, thunder) plus a clear-weather ambience that crossfades day and night
UnityEvents for every time and weather change - wire street lights, shops or cutscenes without code
Also included

Depth-based lens flare occlusion that works with foliage and fades with the sun
A demo scene with an ocean shader, first-person and free camera, and a test HUD for every feature
Custom inspectors for every module, a scripting cookbook and a full PDF manual
Built for Unity 6 and URP 17 with Render Graph. PC and console; mobile is not supported in this version.

Whether you're building a stylized fantasy world, a colorful low-poly environment, or a high-quality cinematic scene, Easy Weather is designed to give you full artistic control over the atmosphere while keeping the setup simple.
