About this project
What does Nuit Interop add?
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.
