Nuit Interop

Formerly known as FabricSkyBoxes Interop

Nuit Interop provides compatibility for OptiFine/MCPatcher custom skies, allowing them to work seamlessly with Nuit — the modern, multiloader successor to FabricSkyBoxes.

This mod enables out-of-the-box support for existing OptiFine resource packs and will soon also offer backward compatibility with legacy FabricSkyBoxes packs.


✨ Features

  • 🔁 OptiFine/MCPatcher Conversion
    Automatically translates custom skies from OptiFine or MCPatcher resource packs to Nuit’s format at runtime.

  • 🧠 Smart Fallback
    Will not convert if a native Nuit/FabricSkyBoxes-format skybox is detected in the resource pack.

  • ⚙️ Flexible Control
    Lets users disable loading native Nuit-format skyboxes in favor of converted ones, for testing or override purposes.

  • 🏛️ Legacy FSB Support (Upcoming)
    Planned support for loading FabricSkyBoxes-formatted packs, helping users migrate gradually.

⚠️ Disclaimer

Conversions are best-effort and may not be pixel-perfect due to fundamental differences between how OptiFine and Nuit handle sky rendering.
