Description
# Nuit Interop
_Formerly known as **FabricSkyBoxes Interop**_
**Nuit Interop** provides compatibility for **OptiFine/MCPatcher custom skies**, allowing them to work seamlessly with [Nuit](https://modrinth.com/mod/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.
