Adds a live view world map into the game with functions and customizable keybinds.

Press the M button to toggle the map on and off.

While the map is open you can press Q to zoom out once and then E to zoom back in.

While the map is open you can press R to toggle the water on and off.

You can walk around and move the camera while the map is open, the map view updates in real time.

Customizatizon

Ignore this portion if you don't care about customization.

Navigate to "%LOCALAPPDATA%\Subnautica2\Saved\Config\Windows\". Easy way to go there is to paste this in Windows Explorer's address bar and then press enter.

Otherwise the path should be something like this:

C:\Users\*YourUsername*\AppData\Local\Subnautica2\Saved\Config\Windows\

(Replace YourUsername with your user's name.)

Once you're there you should see a file named "Engine.ini".

If there's no such file then create one but make sure you're using the correct file extenstion and not Engine.ini.txt.

You could instead copy and paste the GameUserSettings.ini file, rename the copy to Engine.ini/Engine and then delete its contents if you don't know about file extensions.

Open the file with a text editor like Notepad and paste these lines in it:

[/Game/Mods/WorldMap/ModActor.ModActor_C]
OpenMapKey=M
ZoomOutKey=Q
ZoomInKey=E
ToggleWaterKey=R

You can find valid keys to use here: Unreal Engine Fkeys - Pastebin.com
All of them should work theoretically, at least the keyboard and the gamepad keys should work for sure.

Once you're done customizing the keybinds you need to set the file Engine.ini to Read-only otherwise the game is going to delete it!

Notes

Because the game uses Lumen lighting and I wanted to preserve the game's visuals and lighting in the map's view, every time you open the map, for the first 1.5 seconds performance might drop. This is because for the first 1.5 seconds the map system captures the scene on every frame until lumen and eye adaptation stabilizes. After that the scene's lighting has been fully calculated and the map system does simple captures every 3 seconds (only while it is open).

Depending on your system there's a chance you might see a slight performance drop in general when the map is open. The map texture is a 2048x2048 texture, that's updated every 3 seconds, so you might notice a micro stutter when that happens. You're not really supposed to move around with real time maps this size, but I really wanted to be able to walk around and move the camera while the map is open so I left it like this.

Be aware that you can still somewhat activate/use your tools while in the map view. I left it this way because it was the only way to still be able to walk around and move the camera while tha map is open. Just avoid clicking the right click while the map is open but even if you do click it nothing catastrophic should happen lol.

Visibility in the map's view was non-existent at night. I've compensated that by artificially boosting some post processing settings in the map's view but I didn't go overboard so that it still feels different than day. Be aware that mods that modify day/night cycles/hours/duration might break this system (for example my longer daytime mod had an issue that caused this system to break so make sure to use its latest version 1.0.0.1).

Be aware that you might see some oddities on the map. For example the deep starting area where the introduction takes place looks weird when water is disabled and some parts of the map where the temperature is high look weird when the water is enabled.

Installation instructions for Blueprint mod loader

Use either the blueprint mod loader or UE4SS to load the mod.

Download and install the Blueprint mod loader.

Download the mod and extract its .zip file.

Go to where your game is installed and navigate to \Subnautica2\Content\Paks.

Make a new folder named "~mods" in here if you don't have one already.

Drop WorldMap.pak, WorldMap.ucas, WorldMap.utoc from the .zip archive in there.

In the end it should look like this:

\Subnautica2\Content\Paks\~mods\WorldMap.pak
\Subnautica2\Content\Paks\~mods\WorldMap.ucas
\Subnautica2\Content\Paks\~mods\WorldMap.utoc

Navigate to "%LOCALAPPDATA%\Subnautica2\Saved\Config\Windows". Easy way to go there is to paste this in Windows Explorer's address bar and then press enter.

Otherwise the path should be something like this:

C:\Users\*YourUsername*\AppData\Local\Subnautica2\Saved\Config\Windows\

(Replace YourUsername with your user's name.)

Once you're there you should see a file named "Engine.ini".

If there's no such file then create one but make sure you're using the correct file extenstion and not Engine.ini.txt.

You could instead copy and paste the GameUserSettings.ini file, rename the copy to Engine.ini/Engine and then delete its contents if you don't know about file extensions.

Open the file with a text editor like Notepad and paste these lines in it:

[/Game/Loaders/SN2_ClientBPLoader/WBP_SN2_BPLoader.WBP_SN2_BPLoader_C]
Mods=WorldMap

If you used the loader already with other mods then all you need to do is to add the line "Mods=WorldMap" under the loader entry.

When you're done you need to save the file and set it to Read-only otherwise the game is going to delete it!

Installation instructions for UE4SS

Use either the blueprint mod loader or UE4SS to load the mod.

Download UE4SS from UE4SS - Subnautica 2 at Subnautica 2 Nexus or Releases · Subnautica2Modding/Subnautica2-UE4SS · GitHub.

To install UE4SS you need to extract its .zip archive and then go to where your game is installed and navigate to this path: \Subnautica2\Binaries\Win64. Drop the extracted files here. In the end it should look like this:

\Subnautica2\Binaries\Win64\dwmapi.dll
\Subnautica2\Binaries\Win64\ue4ss

Download the mod and extract its .zip file.

Go to where your game is installed and navigate to \Subnautica2\Content\Paks.

Make a new folder named "LogicMods" in here if you don't have one already.

Drop WorldMap.pak, WorldMap.ucas, WorldMap.utoc from the .zip archive in there.

In the end it should look like this:

\Subnautica2\Content\Paks\LogicMods\WorldMap.pak
\Subnautica2\Content\Paks\LogicMods\WorldMap.ucas
\Subnautica2\Content\Paks\LogicMods\WorldMap.utoc

Troubleshooting

If you have any issues with the mod you first need to make sure that ue4ss is running. Navigate to \Subnautica2\Binaries\Win64\ue4ss and look for a file named "UE4SS.log". If there is no such file and you've already ran the game then that mean that UE4SS was not installed correctly.

If there is, you can open that file with a text editor like Notepad and check for errors. If the mod is installed correctly and UE4SS is loading it then you should see something like this in it:

[2026-04-15 14:11:07.4615263] [Lua] [BPModLoaderMod] Loading mod: WorldMap
[2026-04-15 14:11:07.4660481] [Lua] [BPModLoaderMod] Actor: ModActor_C /Game/Maps/L_ClientLobby.L_ClientLobby:PersistentLevel.ModActor_C_2147480638

If not then you probably didn't install the mod correctly.

If you want you can upload the contents of that file on Pastebin.com and then share the pastebin link in a comment explaining your issue.
