AtmosphereFX: Dynamic 2D Weather & Lighting for Unity (URP)

AtmosphereFX is a Unity 2D toolkit for dynamic lighting and weather control built specifically for projects using the Universal Render Pipeline (URP). It manages global lighting transitions across a full day/night cycle and supports animated weather states including Clear, Rain, and Snow.

The system is driven entirely by ScriptableObject profiles, allowing full customization of lighting curves, gradient colors, particle effects, and ambient audio without editing a single line of code. Utility components like RandomWeatherController and WeatherTrigger provide event-driven or automated transitions for seamless integration into UI buttons, cutscenes, or background simulation.

This package includes:

• Lighting and weather manager (singleton)

• Day/night profile system with curve + gradient editors

• Scriptable weather profiles for FX and sound

• Sample prefabs (rain and snow)

• Sample scene with working buttons

• PDF quick-start guide and README

Requires Unity 2022.3 or later with URP 2D enabled. A Global Light 2D must be present in the scene for lighting control to function.
