AION 2 Export/Edit/Import (1 Viewer)

[Ангел Мечты]

Hello everyone. I'm playing AION 2 on the Taiwan server and planning to play on Steam Global. Playing in Taiwan is getting boring, and I'll be leaving soon. I've been meaning to figure out how to unpack AION 2 files, check out the costumes, bodies, and textures. Now I've gotten around to it, and I'm sharing the results with you. It's unlikely anyone doesn't know or can't do what I'm sharing here, but still. I've been working with deepseek for a long time and have gotten used to doing everything in the command line, and honestly, it's easier that way. That's why you'll see command line codes in this guide. I hope everything is clear.
Important: all file paths will be your own; I'm providing the paths as an example, so don't make any mistakes. AION 2 is identical to Blade & Soul in terms of model structure. I don't want to deal with that anymore; I'm done with Blade & Soul, thanks. In the archive attached to the message, you will find the necessary software.



FULL PROCEDURE: UNPACKING → EXPORTING → PACKING THE MOD

STAGE 1: UNPACKING GAME RESOURCES
1.1 Launching umodel
Open the folder F:\AION_Unpacker\FModel\

Launch it umodel_materials_ue5.exe

In the settings, specify:

Game: Unreal Engine 5.3

AES Key:

06038EF544B6007614F8574F1B7C2A3F0D565F74CDCC1B366B4EA1A17B97CBFF

Mapping File: specify the path to AION2-5.3.2.0.usmap

Path: C:\Program Files (x86)\NC\AION2_TW\Aion2\Content\Paks

1.2 Exporting the model
In umodel, go to the folder: AION2/Content/Character/Player/GF/Armor/0000/GF_0000_T01/

Select the necessary files (for example, GF_0000_T01_Body.uasset, GF_0000_T01_Boots.uasset, etc.)

Click Export → select the ActorX (psk) format

Specify the folder to export: F:\AION_Unpacker\UmodelExport\

Click OK


Result: The UmodelExport folder will appear .psk models and .tga textures.
STAGE 2: EDITING THE MODEL (OPTIONAL)
Install the plugin for Blender: Blender PSK/PSA Importer

Open Blender → import the .psk file

Make changes (position, size, shape, etc.)

Export it back to .psk (save it to the same folder)

STAGE 3: PREPARING THE STRUCTURE FOR THE MOD

3.1 Create a fashion folder

New-Item -Path "F:\AION_Unpacker\MyMod\Aion2\Content\Character\Player\GF\Armor\0000\GF_0000_T01" -ItemType Directory -Force

3.2 Copy the model files

Copy-Item -Path "F:\AION_Unpacker\UmodelExport\Character\Player\GF\Armor\0000\GF_0000_T01\*.psk" -Destination "F:\AION_Unpacker\MyMod\Aion2\Content\Character\Player\GF\Armor\0000\GF_0000_T01\"

3.3 Copy the textures (if available)

Copy-Item -Path "F:\AION_Unpacker\UmodelExport\Character\Player\GF\Armor\0000\GF_0000_T01\Materials\*" -Destination "F:\AION_Unpacker\MyMod\Aion2\Content\Character\Player\GF\Armor\0000\GF_0000_T01\Materials\" -Recurse

The structure should be:

MyMod/
└── Aion2/
    └── Content/
        └── Character/
            └── Player/
                └── GF/
                    └── Armor/
                        └── 0000/
                            └── GF_0000_T01/
                                ├── GF_0000_T01_Body.psk
                                ├── GF_0000_T01_Boots.psk
                                ├── ...
                                └── Materials/
                                    ├── GF_0000_T01_Body.tga
                                    └── ...

STAGE 4: PACKING THE MOD


4.1 Go to the tools folder

cd F:\AION_Unpacker\Tools

4.2 Packaging via repak

.\repak.exe pack "F:\AION_Unpacker\MyMod" "F:\AION_Unpacker\MyMod_P.pak"

4.3 (Optional) Conversion to IoStore
If the game uses IoStore (Aion 2 uses it), create .utoc/.ucas:

.\retoc.exe to-zen "F:\AION_Unpacker\MyMod" "F:\AION_Unpacker\MyMod_P.utoc" --version UE5_3

Result: The MyMod_P.pak (and possibly .utoc + .ucas) files will appear.

STAGE 5: INSTALLING THE MOD IN THE GAME

5.1 Copy the mod files

Copy-Item -Path "F:\AION_Unpacker\MyMod_P.pak" -Destination "C:\Program Files (x86)\NC\AION2_TW\Aion2\Content\Paks\"

If you created it .utoc/.ucas:

Copy-Item -Path "F:\AION_Unpacker\MyMod_P.utoc" -Destination "C:\Program Files (x86)\NC\AION2_TW\Aion2\Content\Paks\"
Copy-Item -Path "F:\AION_Unpacker\MyMod_P.ucas" -Destination "C:\Program Files (x86)\NC\AION2_TW\Aion2\Content\Paks\"

5.2 Verification

dir "C:\Program Files (x86)\NC\AION2_TW\Aion2\Content\Paks\MyMod_P*"

STAGE 6: LAUNCHING THE GAME AND CHECKING
Launch Aion 2

Check if the costume has changed

If everything works, the mod is installed successfully!
