00 Create Workspace *.pak files - yozozchomutova/AstroModdingKit GitHub Wiki

Prepare

Your first task is to download unreal_pak_cli. You can find it in home page - Required tools section. Another task is to locate game folder and It's data. For steam, most of the time It's located in: C:\Program Files (x86)\Steam\steamapps\common\ASTRONEER\ Otherwise, game location depends where did you installed it.

Making your workspace

Now you have downloaded unreal_pak_cli and located game directory, now we can make your main folder, where all modding work will happen. Location and folder name doesn't matter (In my case, location is inside my Documents and It's named AstroneerModding). This folder will be your workspace.

unreal_pak_cli

Extract contents of unreal_pak_cli.zip into your new workspace folder. Using this tool is very simple:

  • You click & hold *.pak file, drag it into unpack.bat, it will create folder with extracted data.
  • You click & hold folder, drag it into repack.bat, it will pack folder into *.pak.

Game data .pak

Now you know what it does, so go in original game's directory to ...\ASTRONEER\Astro\Content\Paks\, you will see there 2 *.pak files, grab that huge one (has over 2 GBs and should be named Astro-WindowsNoEditor.pak) and drag it straight into the unpack.bat. Move new generated folder into your workspace/modding folder.

Other tools

In the next tutorials, we'll be using UAssetGUI. Make sure to get it and I recommend you to extract it in your workspace folder, just for the easier access.

Final look

Your workspace folder should look atleast like this:
