# Nuit Interop
\n_Formerly known as **FabricSkyBoxes Interop**_<\/p>\n
**Nuit Interop** provides compatibility for **OptiFine\/MCPatcher custom skies**, allowing them to work seamlessly with Nuit \u2014 the modern, multiloader successor to FabricSkyBoxes.<\/p>\n
This mod enables out-of-the-box support for existing OptiFine resource packs and will soon also offer **backward compatibility with legacy FabricSkyBoxes packs**.<\/p>\n

## \u2728 Features<\/p>\n
– \ud83d\udd01 **OptiFine\/MCPatcher Conversion**
\n Automatically translates custom skies from OptiFine or MCPatcher resource packs to Nuit\u2019s format at runtime.<\/p>\n
– \ud83e\udde0 **Smart Fallback**
\n Will not convert if a native Nuit\/FabricSkyBoxes-format skybox is detected in the resource pack.<\/p>\n
– \u2699\ufe0f **Flexible Control**
\n Lets users disable loading native Nuit-format skyboxes in favor of converted ones, for testing or override purposes.<\/p>\n
– \ud83c\udfdb\ufe0f **Legacy FSB Support (Upcoming)**
\n Planned support for loading **FabricSkyBoxes**-formatted packs, helping users migrate gradually.<\/p>\n

##### \u26a0\ufe0f Disclaimer
\nConversions are **best-effort** and may not be pixel-perfect due to fundamental differences between how OptiFine and Nuit handle sky rendering.<\/p>\n
