A modular 2D weather system for Unity with smooth transitions, wind-driven effects, lighting, fog, and editor tooling.This asset is built and tested with Unity 6.x using the Universal Render Pipeline (2D Renderer).Built-in Render Pipeline is not supported.HDRP is not supported.Timbeaux’s 2D Weather Toolkit is a modular, runtime-driven weather system designed for 2D games using the Universal Render Pipeline (URP).It provides smooth, believable transitions between weather states without visual popping, while remaining easy to integrate and extend. Wind is treated as a first-class system and influences clouds, rain, snow, fog effects, and ambient audio.The toolkit is built around a clean architecture:One authoritative weather stateOne transition manager that owns interpolationAll visual and audio systems react to weather, never control itThis makes behavior predictable, extensible, and safe to integrate into gameplay systems.Included weather features:Sunny, Cloudy, Windy, Rainy, Stormy, Snowy, and Foggy statesSmooth weather transitions (no snapping or popping)Wind-driven clouds, rain, snow, and visual effectsSnowflake flyby effects affected by windFog system with player cutout and refillThunder and lightning supportGlobal lighting dimming during stormsOptional day/night sun and time integrationEditor & workflow features:One-click setup via an Editor WindowDefaults asset for fast prefab assignmentDemo scene showcasing all weather typesDebug UI for forcing weather and testing transitionsGameplay extensibility:The package includes an example of a weather-reactive NPC (a ghost that appears only during Snowy weather), demonstrating how gameplay elements can respond to weather states without tight coupling.Documentation is included directly in the package, covering quick setup and full system architecture.- Unity version tested: Unity 6.x- Render Pipeline: Universal Render Pipeline (2D Renderer)- Weather types: Sunny, Cloudy, Windy, Rainy, Stormy, Snowy, Foggy- Smooth weather transitions with no visual popping- Wind system with direction, strength, gusts, and wobble- Wind-driven rain, snow, clouds, and visual effects- Fog system with player cutout and mask refill- Snowflake and wind swoosh visual effects- Global lighting dimming during storms- Optional sun and time-of-day integration- Editor setup window and Defaults asset- Demo scene included- Documentation included
