Allows resource packs to define custom skyboxes.
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!

Can I use OptiFine/MCPatcher skybox packs?
Nuit does not support those formats natively. Use tools like MCPatcherPatcher++ or Nuit Interop to convert them.
Is it modpack friendly?
Yes! Nuit is licensed under MIT and fully modpack-compatible.
What happened to FabricSkyBoxes?
FabricSkyBoxes has been rebranded to Nuit to reflect its expanded scope beyond Fabric.
