@Sruffy: Provide the package you have problems with. Though I will not be able to check it until I get home next week.

@DewiMorgan: Even though I can't check it by myself at the moment, people are reporting that the game is using default format for respective engine version, which means 4.27 script from my signature or any compatible tool (like umodel/fmodel) should work with the game without additional steps.

Apologies for the ping, wanted to check if you managed to download the file and have a look at it? Its completely fine if you havent, I can wait for sure.

@Sruffy: This looks like self-invented obfuscation from modders - first entry is corrupted on purpose, so the game will simply skip it, but most tools would be troubled while trying to extract it. You can use attached script or any common tools without batch extracting (both umodel and fmodel can process valid entries separately without any issue).

Update: Updated script now extract everything, including invalid data (which obviously can't be used).

Thank you so very much for this, it actually worked. Would you mind sharing how could I achieve such kind of encryption while packing my pak files.

@Sruffy: It's out of scope of this topic. Besides, the same scheme may not work correctly in some cases and in different games.

I am working on trying to extract Multiversus, I found the AES key and can view the models in UModel, but I'm looking for the config files, subtitles, etc.

Using the QuickBMS unreal_tournament_4_0.4.27c_paks_only.bms script I get the following error:

Code:

Error: the requested amount of bytes to allocate is negative (0xfcf29114)

Last script line before the error or that produced the error:

@ardvent: All works fine here with the provided package. Make sure you didn't accidentally corrupted the script (for example, by trying to embed key in a wrong way) or package itself.

Yeah, I think the issue is that I embedded the key wrong, what's the syntax for this?

Code:

# set your AES_KEY here as text or C string ("\x11\x22...") or umodel hex (0x1122...)
set AES_KEY binary "0x419DFFC484F1CED86842DD4E6DD914F02E3E119725F556C4B9AA44432021A9AC"
putarray 10 -1 ""
math AES_KEY_IS_SET = 1

Edit: Additionally I can list the files, but trying to extract them or write the list to a text file freezes quickbms and nothing happens.

@ardvent: Actually this thing should be adjusted a long time ago. Please try updated script, embedding keys is now supported in more convenient way.

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

Base 4.25 and 4.27 scripts are updated, they can now handle embedded keys set via [set AES_KEY binary ""] option in both common hex (0xAABB...) and C string (\xAA\xBB...) forms - previously only C string representation worked correctly. Note that from now on you don't need to change other option (AES_KEY_IS_SET), it will be handled automatically.

Most scripts from specific scripts bundle will be updated in the same way in a few days.

Firstly, thank you for all your help. I wanted to bring in your notice that the script you provided works pretty well for some pak files but there are some which still gives the same error. Can there be a generic script which would work for all such pak files?

Hello everyone, I found a new Nexon game called Argent Twilight, requires AES KEY, thanks!

@Sruffy: I don't want to bother with it much, so I've updated the script in the post above to extract everything from such packages, including invalid data. Different people are using different obfuscations, which can't be properly combined in one script. It's up to you to find out invalid data among extracted assets.

@JackDev: Those requests belongs to the separate topic from my signature.

A lot of scripts from specific scripts bundle had been updated with more convenient way to embed keys. For more info read previous announcement.

Hello. I'm having a problem with the game ?????. This game uses Unreal Engine 5. I used FModel to extract the assets (the assets are in the .ucas file). But I don't know how to pack or mod. I have tried some ways like repacking into a .pak file but it doesn't seem to work. I've also tried searching online but haven't found any useful information yet.
Thanks ~~

I'm not aware of any mod with native assets for UE games using zen store packages (utoc/ucas) - probably because format itself is complex - but I'm not into modding in general. Anyway, modding questions are out of scope of this topic, it's better to ask them at some modding communities.
Also, to avoid certain confusion and to comply with documentation - currently this feature is officially called "io store" in packaging settings, while "zen store" now belongs to net storage service.

There are also some details in this post, for better understanding why modding this format would be problematic.

I was looking for something to extract the audio from Dead By Daylight ( UE4 4.27) can anyone advise me? I don't know if it will be possible with quickbms with some script

spiritovod, posted Thu Aug 25, 2022 9:10 pm (73178)

@sanderson169: I suggest to take a look at fmodel, because it supports wwise audio in UE4 games out of the box. From quickbms side you can extract packages with 4.27 script, available via my signature, but unlike fmodel, you'll need to process extracted audio files with other third-party tools like vgmstream.

Script for Super People is updated in specific scripts bundle, now it works properly with all packages and requires quickbms 0.12 by default. You need to launch quickbms with -C argument for more convenient usage of the script.

I have looked at it and I have doubts. Fmodel is able to put the corresponding name to the audio files? I have seen that Fmodel extracts the audio files but they are called "7826627" and I have no feedback on what they are called.

@sanderson169: Some games simply strip this info upon building the client - try to find related files, like soundbanks.xml/json in packages (it's not exact name), if they're not present, you can't get proper names. But if such files exists, you can use something like this.

Do you have a tool for extracting the last client of the Zuyxiaoyao game? if you have could you share it with me?
