Day/Night Cycle + Weather System is a modular environment solution for Unity developers who need full control over time of day and weather conditions in their projects.

This asset provides a real-time day and night cycle with smooth sun and moon rotation, dynamic lighting changes, and blended day/night sky transitions. It also includes a flexible weather system with ready-to-use Rain, Snow, and Fog presets based on ScriptableObjects, making it easy to customize and extend for different project needs.

The system is designed to be easy to integrate into both small and large projects. Time progression can be paused, resumed, sped up, slowed down, or manually set at runtime. You can also trigger events at specific hours, which makes the asset useful for gameplay systems such as NPC schedules, enemy spawning, quests, shop opening hours, survival mechanics, and environmental storytelling.

The package is suitable for a wide range of genres, including survival, RPG, simulation, open world, sandbox, strategy, and adventure games. It is also beginner-friendly, while still being clean and modular enough for advanced developers who want to expand or adapt the system for their own pipelines.
