Stellara

Stellara is a client-side visual mod that replaces Minecraft's default night sky with custom skyboxes that depend on the biome or dimension. The mod adds stars, planets, moons, constellations, shooting stars, auroras, sky color tints, light ribbons, and other decorative elements to the sky. In different biomes, the sky may vary in color, object set, and overall atmosphere. The skybox system is data-driven: all sky variants are defined using JSON files and can be delivered through datapacks. These files allow you to create new skyboxes, change the conditions under which they appear, configure visual layers, and combine different types of sky objects without modifying the mod's code.
