Allows you to pause the game with the F4 button (customizable).

Done efficiently and natively with Unreal Engine's blueprints!

No loops running constantly in the background affecting performance.

True pausing using unreal engine's functions instead of time dilation-based slowdown!

Customizatizon

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

Navigate to "%LOCALAPPDATA%\Solarpunk\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\Solarpunk\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/Pause/ModActor.ModActor_C]
PauseKey=F4

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.

Notes

The mod uses pakchunkID 9825. This means that it is incompatible with any other mod that uses the same pakchunkID.

Installation

Download and install UE4SS Solarpunk.

Download the mod and extract its .zip file.

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

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

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

In the end it should look like this:

\Solarpunk\Content\Paks\LogicMods\Pause.pak
\Solarpunk\Content\Paks\LogicMods\Pause.ucas
\Solarpunk\Content\Paks\LogicMods\Pause.utoc

Troubleshooting

If you have any issues with the mod you first need to make sure that ue4ss is running. Navigate to \Solarpunk\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: Pause
[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.
