Simple Minimap adds a lightweight in-game minimap to Subnautica 2, with a player marker, heading indicator, and an optional large map view.

The minimap is rendered directly on the HUD using UE4SS Lua scripting. By default, it appears in the top-right corner of the screen and can be toggled on or off at any time. A larger centered map view is also available for quick navigation.

This mod uses UE4SS, so you need to install UE4SS - Subnautica 2 first:

https://www.nexusmods.com/subnautica2/mods/36

Features

Controls

Default keybinds:

M — Open / close the large map
H — Hide / show the minimap

These can be changed in config.lua.

The mod registers the configured keys from config.lua, where OpenMapKey is set to M and HideMapKey is set to H.

Go to your Subnautica 2 install folder.
Open the UE4SS mods folder:

Subnautica2/Binaries/Win64/ue4ss/Mods/

For Game Pass / WinGDK versions, the folder may be:

Subnautica2/Binaries/WinGDK/ue4ss/Mods/

Create a folder named:

SubnauticaMapMod

Place the mod files inside:

SubnauticaMapMod/

└── all lua

Configuration

see config.lua

Vortex bug

For reasons I don't know, Vortex ignores anything that isn't a .lua file, so .png files will be called .png.lua.

Troubleshooting

The minimap does not appear

Make sure UE4SS is installed correctly.
Make sure main.lua and config.lua are directly inside the SubnauticaMapMod folder.
If you are experiencing FPS issues, you can increase the UpdateIntervalMs value in the config file.
