Celestial Skys
Celestial Skys changes how the sun, moon and night sky look, and adds solar and lunar eclipses that are scheduled at random.
What it does
The mod replaces the sun and moon with rounder, detailed textures. The sun is drawn as a smooth disc with a warm tint, close in size to vanilla. The moon shows visible craters and darker surface regions, and its lunar phases shift with a faint earthshine on the shaded side. The sun and moon follow a curved path from east to west, and the night sky shows small changes in the brightness and colour of its points of light. Moon halos appear when thin clouds pass overhead, and sunsets can show a rare green flash, a faint zodiacal light and airglow near the horizon.
Eclipses are scheduled at random, with configurable chances. Partial eclipses differ in their maximum coverage, and total eclipses are included. During a solar eclipse the light level falls by an amount that depends on how much of the sun is covered, and totality lowers it sharply, while partial eclipses also affect it. The mod's commands under celestial start, stop and check eclipses, so a server owner can trigger one instead of waiting. Celestial Skys requires Fabric API on the Fabric loader. The mod is published for Fabric and NeoForge, for 1.20.1 and 1.21.1.
