Nuit (formerly FabricSkyboxes)

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 now full support for both Fabric and NeoForge!

Design immersive skies with dynamic day/night cycles, custom fog, sunrise/sunset glow, and more — all backed by a robust, extensible skybox format.

⚠️ Nuit is currently in beta. Some features may evolve over time. Feedback is welcome!
