🌐 About

Nautilus is a modding library that aims to enhance developer productivity by offering common helper utilities as easy to use and robust as possible. Notable systems which Nautilus offers: Adding/editing items, implementing custom sprites & textures, custom audio, a Subnautica-styled mod configuration menu, and so much more!

This project is a continuation of SMLHelper with an improved codebase and maintainability. Nautilus offers all the features SML used to offer in a more robust implementation. Additionally, Nautilus took another route of managing handlers to fix many bugs and timing issues that were persistent in SML.

We hope to keep improving the modding experience in Subnautica to allow developers to create mods more easily and eliminate the implementation concerns in the mod-making process. For more information on Nautilus and its capabilities, please refer to our documentation.

⚠️ Nautilus is only supported on the latest version of Subnautica. If you're playing on the Legacy branch via Steam, use SMLHelper instead.

⬇️ Installation

1. Download the Subnautica BepInEx Pack.

2. Extract/unzip the BepInEx x64 zip file to your game folder

   • Where is my Subnautica/game folder?

     • Steam:         C:\Program Files (x86)\Steam\steamapps\common\Subnautica
       
     • Epic Games:   C:\Program Files\Epic Games\Subnautica
       
     • Xbox PC:       C:\XboxGames\Subnautica\Content
       

     Note: the above paths are the default locations, yours may vary

   • How do I extract the zip file?

     • Extracting/unzipping a zip file is as simple as right clicking it, and selecting the Extract here prompt. We highly recommend the use of a zipping tool besides the Windows default one, such as WinRAR, or 7-Zip.

3. Download Nautilus from Nexus Mods, Submodica or GitHub Releases (this link will be updated later when Nautilus is released).

4. Extract/unzip the Nautilus zip file to your Subnautica\BepInEx folder

5. Confirm your Subnautica\BepInEx\plugins now looks like this:

   If it doesn't look like this, try figuring out where your Nautilus folder has gone, and move it into the plugins folder

   

6. Launch the game, and enjoy! (a good way to confirm Nautilus has loaded is to check the game Options for a Mods tab)

If you have any trouble installing the mod, please join our Discord server, and explain whats going on in a help and support channel.
