What do I do once I've extracted the paks to get uassets?

[spiritovod]

@TopHat: Could you be more specific? uassets are native UE assets and it's what you're getting after extracting paks, among other files. If you're trying to find some particular files, which are not supported in umodel/Fmodel directly, it's most likely not uassets you need.

[TopHat]

@spiritovod I'm trying to get the sound files from Sea of Thieves and when using the sot specific script it extracts uassets.

[spiritovod]

@TopHat: As far as I know, in Sea of Thieves most audio is stored in wem files. I don't know where exactly though, so you probably need to extract all paks and search for those files with the help of some file manager. They can be played and converted with vgmstream directly or foobar with vgmstream plugin.

To simplify extraction (as the game has 1000+ paks), you can embed the key in the script, just edit the script like this:
[set AES_KEY binary ""] -> [set AES_KEY binary "\xAA\xBB\xCC"] where 0xAABBCC is the actual key
[math AES_KEY_IS_SET = 0] -> [math AES_KEY_IS_SET = 1]
and then use it with batch file like this:
quickbms_4gb_files.exe -F "{}.pak" you_script.bms "input folder with paks" "output folder"

[TopHat]

@spiritovod When I extracted the paks I did indeed get a folder full of numerical wem files in the "Streams" folder and the other folders had specifically named uassets.

I'll use that tool with the wem files. My question is are those wem files in the Streams folder just the same as the uassets in the other folders just without proper names?

[spiritovod]

@TopHat: If these uassets are relatively small, they are most likely contain info about wem files and control schemes, as UE can't read such wwise format directly. If you have more questions about already extracted audio, feel free to create separate topic at Audio format section of the forum, since this topic is for general issues with UE packages, including encryption and extraction.

Bloodhunt AES keys ? Please and thanks!

[spiritovod]

@DJ Normality: I've added the key to the list (available via my signature), but the package has custom format and current scripts are not compatible with it. I'll take a look at it later, the issue looks similar to Scavengers (though that script also doesn't work properly here).

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

Bloodhunt script added to specific scripts bundle. Though one file seems bugged and it will not be extracted.

Thank you working good!! I did make a account for that site your on. Very cool. You have helped me do many titles. Also I organized the keys differently they do seem easier to read. The new ones in [update] I found randomly I think some are there but others are not. So them just need organized. Anyway. Thanks again for all you do and I really appreciate this one. Any news on Tony Hawk 1&2 HD ? I found 34 keys in that game but I cant seem to dump the assets with any of them. When you got time of course.
I started doing BloodHunt and noticed Umodel fails so the only way to get anything is by batching the files and im still not seeing any meshes. Maybe I just havent reached them yet.

**update**

I did find meshes so im happy

what did you use to view the meshes?

[spiritovod]

@DJ Normality: I understand your concern about list format, but due to forum's format limitations and automatic line breaks in case of high scale settings or viewing in portrait mode suggested representation will be much harder to read, compared to the current one.
If you mean latest THPS 1 + 2 game (HD are remakes from 2012 & 2016), you can read about it in this topic and this post.
And next time please don't directly insert screenshots like this, you can attach them to your posts or provide links for them at image hosting.

@Lx22: Bloodhunt is supported by umodel (after extraction), since it's a UE4 game, there is a topic for it here. If you have other questions about particular assets (like models), feel free to ask in respective forum sections, since this topic is for general issues with UE packages, including encryption and extraction.

The files inside the pak archives aren't encrypted.
Have you tried to just press RETURN when quickbms tells you to select the encryption key?

Hello, can someone help me to find AES key. (Police Simulator: Patrol Officers)

[spiritovod]

@lokakam: The game is not encrypted - just use 4.26 script from the post in my signature, it should work.

[spiritovod]

@DJ Normality: It's not an UE game. Also, there is a topic for it already.

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

I've updated 4.26 script, it now handles more default flags. It should fix an issue with Orcs Must Die 3 and other games like this.

I'm stuck on Back4Blood's new PAK format.
Neither the official Unreal 4 BMS script or spiritvoid's script works.
The PAK files are packchunk#-WindowsNoEditor.pak and contain .sig signature files.
The Engine version is 4.25

I uploaded pakchunk0-WindowsNoEditor.pak for testing: https://www.filemail.com/d/qrdnjwjslmnblnu

File in a hex editor:


quickbms -l output:

Code: Select all

quickbms.exe -l unreal_tournament_4_0.4.25b.bms 'F:\SteamLibrary\steamapps\common\Back4BloodBeta\Gobi\Content\Paks\pakchunk0-WindowsNoEditor.pak'

QuickBMS generic files extractor and reimporter 0.11.0

- open input file F:\SteamLibrary\steamapps\common\Back4BloodBeta\Gobi\Content\Paks\pakchunk0-WindowsNoEditor.pak
