@Pepita: It seems you're doing it wrong way.
1) If you want to include modified ini with u4pak:
For example, this ini was originally in pakchunk0-WindowsClient.pak. Create folder structure Mod\AOC\Config\DefaultEngine.ini (so it will contain only this single file), put u4pak.py in the Mod folder (so it will be near AOC folder), then run cmd from the Mod folder and execute "u4pak.py pack pakchunk0-WindowsClient_mod.pak AOC". Now you have pakchunk0-WindowsClient_mod.pak in the Mod folder with modified ini. Put that pak with the rest of them. If they have .sig files (for example, pakchunk0-WindowsClient.sig), simply create copy of it with required name (pakchunk0-WindowsClient_mod.sig in this case).
2) If you want to do the same with unrealpak, take FluffyQuack's workflow (from the first link in my previous post) and drag-drop Mod folder on UnrealPak-Without-Compression.bat. You can replace unrealpak with any other version from UE SDK, available for free from epic games (it's all explained in the second link).

Note that: If you don't know how signing works, do not sign archives, just re-use existing signatures with unsigned paks (it works too, unless the game has additional checks). You can't repack the whole game, it doesn't work. Packing level is different for u4pak and unrealpak in some cases (AOC and parent folder, Mod, in the example). Paks are prioritized in reverse alphabetical order, hence the _mod addition - it's not mandatory, you can name it other way.


Thanks a lot, that actually worked :)
So I got the Pak naming wrong basically and not the Mounting points etc. I just called them pakchunk0-something.

@Wilps: Sorry, but did you even try to google? The game is using CryEngine, paks can be extracted with 7zip/Winrar and content is not encrypted, but rather has specific formats (example).
Also, your files are not available for download.

@cj123: The game is using UE3, not UE4, with modified encrypted resources. I'm not familiar with UE3 at all, so can't help you with that. Also, I don't think that creating additional topics for the game and bumping it every day (there is already one) will help you either.

@Puterboy1: You can find it in the list from my signature. Also I suggest you to try AES finder (also available via my signature) for future updates.

@Julayi: No game title, no sample, nothing? Anyway, if you can't find the game in the list from my signature, you're out of luck, since nobody is extracting aes keys from mobile games nowadays (at least for UE4 games), aside from very rare exceptions.

@Julayi: All mobile and desktop versions of pubg can be extracted with specified scripts, available in the post from my signature. Mobile and lite version are not encrypted, so only certain scripts are required, and the key for desktop version is also available in the list from my signature.

@Xray: Current ACC version is 1.4.4, so not sure what you're trying to unpack. Read my signature, you can find key for the latest version there (also compatible with a few previous versions). If you're trying to unpack some old build with different key, use AES finder to find the key.
In case if you don't need maps, just models, use umodel to extract corresponding stuff.

Script for chinese pubg mobile (aka "game for peace") added to base post: viewtopic.php?f=9&t=1005&p=56251#p56251
Note that ini files will be encrypted after extraction, since I don't have a proper key for the game. The rest of assets should be fine.

Hi guys!
Please help unpack Unreal Tournament 4.
I need gun models and textures from there.
I used umodel.exe, as soon as I tried, unpacking does not work at all. The error constantly flies.

Dead by Daylight Mobile key added to the list. Grabbed from version 3.7.20, but should be compatible with almost all previous versions as well.

Traha key added.
Update: Key for actual korean version (2.5.5) also added to the list. New key is also compatible with latest japanese version (1.3.6).
Update 2: It appeared that first key is for QoApp game version, so there are two positions in the list now - for playmarket version and qoapp version.

Bless Mobile key added to the list. Grabbed from v1.200.196675, but also compatible with few previous versions. Specific script for Bless Mobile is also added to UE4_bms_specific_scripts bundle (read my signature).

--------------------------------------

It would be nice if someone could test stuff with those asian games and create corresponding topics on Gildor's forum. Complete cache for those games is not available for public, so I tested only small paks included in apk.

@WollieWoltaz: Thanks for clarification. So playmarket and Qoapp versions has different keys.

I've added them both in main list now to avoid confusion (both of them are up-to-date, but for different versions). Previous post is also edited to reflect these changes.
