Astronomic Skybox is a Unity Package for simulating realistic skyboxes. Perfect for recreating real-world places, time lapse effects, impressive day/night cycles, or just stargazing!

Simply drop the Skybox prefab and a TimeManager singleton into your scene and you will have a working skybox! Read the wiki to learn what options are available.

• Accurate positioning of the sun, moon, and stars.
• DirectionalLights to simulate sunlight, moonlight, and ambient light
• Supports three celestial coordinate systems
  • The Horizontal coordinate system is the view from a given point on earth.
  • The Equatorial coordinate system is centered around Earth and its equator. This is what the stars are mapped to.
  • The Ecliptic coordinate system is centered around Earth in this instance and the orbital plane of the planets.
• StarPositioner.cs orients the skybox to be accurate to specific dates, times and places on Earth.
• StarGenerator.cs generates stars and constellations for the skybox.
• StarMath.cs contains a bunch of methods for converting coordinate systems and calculating the position of the sun and moon.
