MODDING

If you want to modding, maybe that helps you: 
 
First I want to say that is the way I modded it. 
Maybe some things are wrong or unnecessary 🙂 
 
In this example I explain how to replace Six with Mono: 
 
You need this tools: 
-Unreal Engine Editor 4.24 (Creator) 
www.nexusmods.com – https://www.unrealengine.com/en-US/download under Main Files, for creating .pak files) 
 
-UnrealPakViewer (to extract your .uasset and .uexp files) 
https://github.com/jashking/UnrealPakViewer/releases 
 
-Any 3D Program that support .psk files (3D model psk files) 
 
1. Open Helios-WindowsNoEditor.pak with Unreal model viewer 
(Example: C:\Steam\SteamApps\common\Little Nightmares II\Helios\Content\Paks\) 
AES Key: 
0x6DB89C80969B2F5512A5CA1837147EDB31440ABBB603BFE0993A7049E73F6A54 
 
2. a. In Unreal model viewer go to Game/Characters/Player and doubleclick on 
SKM_Player02.uasset (that is the model of Mono) 
b. Select Unreal engine 4.24 
c. Then Tools/Export current project (for example as .psk model file, export where you want) 
 
3. Copy all textures-files in the exported ‘Textures’ folder into ‘Player’ folder 
 
4. a. Open your 3D programm and rename there the Mesh SKM_Player02 to SKM_Six 
b. Select all and export it as SKM_Six.FBX like this: 
https://docs.unrealengine.com/Images/WorkingWithContent/Importing/FBX/SkeletalMeshes/max_export_4.webp 
c. Rename now the mesh in your 3D program again: SKM_Six to SKM_Six_Jumper and export it again as SKM_Six_Jumper.FBX 
 
5. a. Open Unreal Engine Editor 4.24 and create a new blank Project 
b. Create there in folder “Content” a new folder named “Characters”. And in “Characters” 2 new folders named “Player” and “Six” 
c. Drag&Drop SKM_Six.FBX file in to the Unreal Engine Editor into folder “Six” and click on “Import” 
d. After compiling Shaders close the Message Log Window 
e. Doubleclick on SKM_Six, search for the Element “MAT_Player_Clothes_ncl1_1” and Replace it with “MAT_Player_Clothes”. 
Because the game not use this generated file. Save it and close the window 
f. You can now delete MAT_Player_Clothes_ncl1_1. If you haven’t such file, ignore it 
g. Rename SKM_Six_Skeleton to SKEL_Player (thats the original Skeleton name) 
h. Move SKEL_Player to the “Player” folder (because the original SKEL for Six and Mono is in this folder) 
i. Move all MAT_ and TEX_ files to “Player” folder (because Mono need his textures and this his folder) 
j. In Menu File/Package Project/Windows (32 Bit) package your project as .pak file 
k. Do step 5 again with the file SKM_Six_Jumper.FBX (new project or just delete all previous files) 
 
6. a. Open UnrealPakViewer and open your first package (the .pak file) 
b. Go to WindowsNoEditor/NAME/Content/Characters/Six/ 
c. Export only SKM_Six.uasset and SKM_Six.uexp 
d. Do that again with your another .pak file 
 
7. a. Copy/cut this exported files and drop it into Helios/Content/Characters/Six folder from the pack_tool 
b. Doubleclick on START_pack.bat 
c. You have now a Helios-WindowsNoEditor_MyMod.pak. Rename it after _ 
d. Copy it to the game folder, where the Helios-WindowsNoEditor.pak is 
e. Copy/paste now Helios-WindowsNoEditor.sig and rename it like your mod (example: Helios-WindowsNoEditor_MyMod.sig) 
 
Start the game and test it!
