Formerly known as FabricSkyBoxes, Nuit is a powerful and flexible custom skybox engine for Minecraft.
It goes far beyond OptiFine's skybox system, offering rich features like keyframe-based transitions, rotation, custom weather rendering, and full support for both Fabric and NeoForge.
Design immersive skies with dynamic day/night cycles, custom fog, sunrise/sunset glow, weather-aware rendering, and more, all backed by a robust JSON skybox format.
Nuit is currently in beta. Some features may evolve over time. Feedback is welcome.
