About

This project exists because many custom sky resource packs are already available for Nuit Fabric Version(or Higher versions of Neoforge) or OptiFine-style formats, while NeoForge 1.21.1 users currently do not have a simple solution. If the official Nuit project releases an equivalent NeoForge version, this port will be archived.

What This Mod Does

NeoforgeSkyboxes loads custom skybox resource packs on NeoForge 1.21.1. It merges the core Nuit/FabricSkyBoxes behavior with Nuit Interop, so both Nuit/FabricSkyBoxes-style packs and OptiFine/MCPatcher custom sky packs can work through one client-side mod.

During the port, a few small compatibility and rendering bugs were also fixed.

How To Use

Install this mod on the client, then enable a compatible custom sky resource pack.

Tested resource packs include:

Dramatic Sky(Demo and Beta) by thebaum64
Hyper Realistic Sky by UsernameGeri
Fresh Skybox by razvangn

Note: If you are using the Beta version of Dramatic Sky and want Nether skies to display correctly, you may also need to install Celestial.

Shader Notes

BSL Shaders can be fully compatible after changing these settings:

Environment > Sky: turn off Sky Desaturation
Environment > Sky: turn offShader End Sky
Environment > Sky: turn on Deferred Sky
Lighting > More Shadow Config: set Sun Path Rotation to 0.0

Other shader packs may work, but need testing. Some shaders render their own sky and may hide custom skyboxes unless their sky options are adjusted.

Support Notice

Issues and compatibility reports are welcome here, especially for resource packs or shader packs that have not been tested yet! Please report problems to this project first, rather than to the official Nuit/FabricSkyBoxes maintainers or resource pack authors, unless you can reproduce the same issue on their officially supported loader setup.
