[HDRP] Day/Night Cycle

Originally based on my YouTube tutorials, this package has evolved into a ready to use solution. It includes advanced features and algorithms not covered in the videos, saving you hours of work on complex calculations and scripting. The included prefabs are ready for immediate use in your scene and everything is built around Unity Physically Based Sky to create a realistic day and night cycle at a low performance cost. Now available in two versions, so you can pick the one that fits your project: - Advanced: a full astronomical simulation built for projects that need real world accuracy. It calculates the actual position of the Sun and Moon based on date, time, latitude and longitude, giving you correct sunrise, sunset, moonrise and moonset times. It also features a complete Moon phase cycle with individually tuned intensities, smooth automatic shadow switching between Sun and Moon, and eight independently configurable twilight zones, each with its own sky color and light temperature. This version is ideal for simulation focused games, open worlds, or any project where the passage of real time, location and season matters. - Simple: it gets you a simplified day and night cycle at a low performance cost. Instead of calculating real Sun and Moon positions from date, time zone and geographic coordinates, this version lets you directly set the Sun and Moon azimuth and elevation and lets you shape every aspect of the lighting intensity, color temperature, sky tint and star visibility. This version is intended for projects where a simple day and night cycle is sufficient and precise astronomical calculations are not required. With "[HDRP] Day/Night Cycle" creating stunning, realistic, and atmospheric environments becomes easy, fast, and enjoyable. All you need is a few seconds and a few clicks to enrich your game or project.
