Nuit Interop
Nuit Interoperability for OptiFine/MCPatcher and legacy FabricSkyBoxes sky formats
About this Mod
Nuit Interop
Formerly known as FabricSkyBoxes Interop
Nuit Interop adds compatibility for OptiFine/MCPatcher custom skies, allowing existing resource packs to work with Nuit, the modern multiloader successor to FabricSkyBoxes.
It converts supported OptiFine custom sky definitions to Nuit’s skybox format at runtime, making many existing sky resource packs work out of the box.
Features
OptiFine/MCPatcher Custom Sky Support
Converts supportedoptifine/skyresource-pack definitions into Nuit-compatible skyboxes.Smart Fallback
Skips conversion when native Nuit/FabricSkyBoxes-format skyboxes are already present.Flexible Control
Includes options for disabling native Nuit-format skyboxes when testing or preferring converted skies.Legacy FabricSkyBoxes Support
Planned support for loading legacy FabricSkyBoxes-format packs directly.
Requirements
Notes
Conversion is best-effort. Some packs may not render pixel-perfectly because OptiFine/MCPatcher and Nuit handle sky rendering differently.

Does Nuit Interop need to be installed on the Minecraft server?
No. Modrinth marks Nuit Interop as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.
Which version and loader does Nuit Interop require?
Use a file for fabric, neoforge, quilt and your exact Minecraft version. Supported versions include 26.2, 26.1.2, 26.1.1. Files for different loaders are not interchangeable.
Nuit Interop is not working – what should I check?
First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
