Как распаковать pak ue4

In this guide I will explain how to access the contents of the game and repackage any modifications made. This guide is inspired by several games that use UE4 that can be modified normally. Besides being able to offer, at least for now, a solution to the need for a change in the game.

Remember that the developers are still working on the game and we have to give them all our support

-You can’t load different maps in the game because you don’t have the programmed entities and tools used in the UE4 editor.

-So far it works quite well with retextures, but it hasn’t been tested yet with reskins

-You cannot modify aspects programmed internally in the game

Unreal Engine 4.21 from Epic Games platform.
Yes, you must download the Epic Games platform and the Unreal Editor, precisely version 4.21.2

With this we will have the basics for viewing and re-exporting custom content for Earthfall

First we must locate the .pak file of the game, this file saves the assets that were created with unreal engine.
For earthfall, this file will be in this directory:

«. \Steam\steamapps\common\Earthfall\Earthfall\Content\Paks\»

Now once we have downloaded Unreal engine 4.21, we must go to the installation directory you selected and locate the file «UnrealPak.exe».
the location of this file is as follows:

«\Epic Games\UE_4.21\Engine\Binaries\Win64\UnrealPak.exe»

This command program will be able to extract the .pak file in a directory that we assign and we’ll control it through the CMD.

Keep in mind that to assign directories or file locations just drag&drop the file to the command window.

To get started you must first know how to run the command to extract the file. This process should be structured as follows:

<«UnrealPak.exe» LOCATION> <.PAK FILE TO EXTRACT LOCATION> -Extract <OUTPUTFOLDER LOCATION>

<«UnrealPak.exe» DIRECTORY>: just open the command window and drag the file «UnrealPak.exe» to the command window. followed by a SPACE.

<.PAK FILE TO EXTRACT DIRECTORY>: We will find the file «Earthfall-WindowsNoEditor.pak» and drag it to the command window, followed by a space and the command «-Extract» and another space.

<OUTPUTFOLDER DIRECTORY>: Create another empty folder where you will save the extracted content and then drag it to the command window

Once everything is ready and looks like the image, you can press ENTER and the pak file will start to be extracted. It will take a while since it’s almost 20GB of content. When the process is finished, you will find all the content in the output folder you created earlier.

Congratulations, you managed to extract the .pak file but you still can’t see the content itself, because the assets are compiled in the format that UE4 editor saves when cooking a project (.uasset and .uexp .ubulk, etc).

NOTE:Don’t try to open the project, you don’t have the source code or the data used by the developers

In order to be able to decompile models and textures with their animations and resources, we must use the UEViewer program. This program is intuitive so I guess you won’t have problems using it, you can browse through the game’s files and see its models with their textures and animations,
but remember to use «override game detection» to the version of ue4 that uses the game

From this point you can edit textures and models in 3D editing programs and image editors. Personally I use Blender and Photoshop but you can use the one you find more comfortable.

Once we’ve modified what we wanted, it’s time to try it out in the game.

We must take into account that the content of the game is read from the .pak file, but we must not go back to repak all the 20GB content that we had previously extracted. In this process we will only export the content that we have modified and make the game include it when it is executed.

Let’s take Danny’s default skin as an example. I decided to make his sweatshirt red instead of gray.

I left the default file name too, now we must convert this texture into the format that UE4 uses to read its ( .uasset, .ubulk, .uexp)

For that we must first open the UE4 4.21 editor from Epic Games and create a new project
Once we have the session ready, we can either drag the new texture into the content browser or use the «import» function and search for the texture

Within that window we can create folders, I recommend creating the folders exactly as the game content was located, for example, this texture was originally in :

«<wherever you’ve stored the unpacked stuff>. \Content\Characters\Humans\Danny\«

This is mostly to make it easier to manage the content you import and maybe necessary for the game to recognize the path of the content.

Once we have the file in its respective folder or not, we will start the packaging process. For that we must go to «File > Cook Content for Windows».

How to unpack and repack Unreal Engine 4 files

Because i couldn’t find any tutorial for this, i made my own package. This tutorial doesn’t include how to unpack NSP, XCI or NCA. It’s for people who already knows that. Use DBI or emulators romfs browser.

This tutorial is made purposely for mount point ../../../ which is default for Switch games. More info in tutorial.
It may look rough, but it’s easy to remember after few attempts.
If something is not working, write post.
English purists should run away. It will not be a plausible text.

1. What you need to download:
   — Package "UnrealPakSwitchv9.zip" from attachments and unpack it.
   — Notepad++ (or any other text editor with Perl regular expressions)
   — Python 2 or 3
   — Unreal Engine 4.19.2 (for v4 *.pak), Unreal Engine 4.20.3 (for v5 *.pak), Unreal Engine 4.21.2 (for v7 *.pak), Unreal Engine 4.22.3 (for v8 *.pak), Unreal Engine 4.24.3 (for v8.23 *.pak), Unreal Engine 4.25.4 (for v9 *.pak), Unreal Engine 4.26.2 (for v11 *.pak), Unreal Engine 4.27.2 (for v11.27 *.pak). For complete pack you need to download eight of them.

The Basics

When creating a project in Unreal Engine 4, the project will be saved to a directory. Within that directory will be the project. For example: <SaveDirectory>/<ProjectName>/… . <ProjectName> houses all of the contents of the Unreal Engine 4 project. In that project folder, there will be a subfolder named Content . That folder houses all of the assets and blueprints within a game.

In the case of Ready or Not, the project name is ReadyOrNot . Within that folder, there is a folder called Content . Again, this houses everything inside a game except for configuration files. However, when you open the game files in UModel, there may not be a Content folder, instead, it’ll have been replaced with a Game folder. When .paking your mod, you should replace Game with Content . Any of the sub folders will remain the same.

The majority of the modding that you will do will be under the Content folder. If a file that you are looking to override is in . /ReadyOrNot/Game/ReadyOrNot/Assets/Weapons/Python , the file path to copy would be . /Content/ReadyOrNot/Assets/Weapons/Python .

Failure to copy the exact path of Ready or Not will result in a broken mod.

File Formats

There are multiple different file formats that you may encounter while modding. Here is a list of most of them, and what each of them are.

• .psk — A skeletal or static mesh. May contain the skeleton.
• .psa — An animation for a specific mesh.
• .uasset — Two types.
  1. Raw .uasset files are the ones created after cooking a UE4 project.
  2. UE4 .uasset files are the ones that are taken directly from a UE4 project, they are uncooked and can be transferred between projects.
• .uexp — An raw complementary file to uassets, usually containing import and export maps.
• .ubulk — Another data storage file that UE4 uses.
• .umap — A level/map file, similar to .uasset in the way that there is an uncooked and cooked version.

Essentials

Extracting Game Files

There are two methods of extracting games files, both have important differences:

. This program can extract non-raw files, allowing you to gain access to textures, models, and animations. To use it, direct it towards the location of the .pak files within Ready or Not: <GameInstallLocation>\Ready Or Not\ReadyOrNot\Content\Paks . You’ll be able to extract individual assets once loaded.
1. Manual unpaking. This can be done simply by setting up an unpak batch script.
   1. Create a .bat file in your UnrealPak install location (located within your Unreal Engine 4 install), usually <InstallLocation>\UE_4.27\Engine\Binaries\Win64\UnrealPak.exe .
   2. In the .bat file, paste the following lines in and save:

   Cooking Modified Files

   In order to override any assets within the game or add new content, the files must be in a format that the game can recognize. The files you extracted via UModel will be in a format that is easily accessible by you, not the game. You will first need to cook these before PAKing the files.

   1. Install the latest version of Unreal Engine 4.27. The current latest version is 4.27.2.
   2. Import all the files you want to pack with your mod into a new blank project. Any other template can work, but will result in significantly longer cooking times.
   3. Go to File > Cook Content for Windows . This converts the files into a UE4 exported format (*.uasset, *.uexp, *.ubulk). Retrieve the cooked files in <ProjectLocation/><ProjectName>/Saved/Cooked/WindowsNoEditor/ .

   Creating a PAK File

   1. Make sure the folder you are paking, for example pakchunk99-Mods_MyMod_P , contains the same file structure as Ready or Not. Also ensure that _P is at the end of your pak name. Not doing so will likely result in the mod not loading. The number after pakchunk indicates the load order of the .pak. Make sure to understand the directory structure first, before paking your mod. Incorrect directory structure will lead to issues. Your structure should mimic something like this: pakchunk99-Mods_MyMod/Content/ReadyOrNot/Assets/… .
   2. Create a .bat file in your UnrealPak install location (located within your Unreal Engine 4 install), usually <InstallLocation>\UE_4.27\Engine\Binaries\Win64\UnrealPak.exe .
   3. In the .bat file, paste the following lines in and save:

   If the .pak file size is 1 KB, change the locations of the contents you are attempting to pak.

   Additional Information

   Mod Installation

   All .pak mods go here. <GameInstallLocation>\Ready Or Not\ReadyOrNot\Content\Paks . Ensure that the .pak load order is correct.

   Example Mod

   To see if your PAKing is working, download this example mod. This will turn your gun on the main menu pink if the .pak is correctly PAKed. Download and extract the .zip file before PAKing.

   Debugging

   If your mod is not working, make sure to check these common error points:
