What it does

Nuit Interop Continued picks up the earlier Nuit Interop project from FlashyReese and extends it to cover the 1.21.5 and 1.21.8 game versions. Its files target Fabric, NeoForge and Quilt, and it requires Nuit and Fabric API. Only the client needs it, and the mod is released under the MIT License, though it is not open source.

Key features

  1. Sky pack conversion

    Custom sky resource packs written for OptiFine or MCPatcher are converted to the Nuit skybox format while the game runs.

  2. Existing packs keep working

    Sky packs that were built for the older format continue to load without being edited by hand.

  3. Bridges the format gap

    Nuit reads its own format directly, so this mod fills in support for the OptiFine layout.
