The script is that 5-lines in "Code:" in my topic.
Copy&paste in a new text file and use it as script.

Your using a older version of uModel, your using 660 while current is 761, however it doesn't really matter is this case, since it's a data only file that uModel can't export out and if you save it out has a uasset you can only see the following.

also UE4.18 is the engine version the game is built on.

I've been trying to extract the .pak file for F13 for a while, and I think that the program is set properly. I'm currently using the UE4 plugin (unreal_tournament_4.bms) and I'm using the 4gb version of QuickBMS, but the issue I'm having is that I don't have the key/AES key needed to decrypt it.
How would I find the AES key needed to extract the file?

Any assistance is appreciated

I'm also looking for F13 AES key, i could not find it in the exe strings
aside de .pak file, this update also includes a .sig file

I would also like to know what are the methods that you guys use to find it

Thanks

Ah just a note about using quickbms on Mac with unreal_tournament_4.bms, because I have seen a post on the gildor's forum regarding a problem with aes http://www.gildor.org/smf/index.php?top ... 9#msg28569
Quickbms is not compiled with openssl on Mac so there is no access to all the known encryption algorithms supported in this library and you can't use this script on this platform (don't ask why, it's a long story).
If you need to use quickbms on Mac with aes encryption you have to compile everything by yourself.

*edit* solution: wait quickbms 0.8.5

Regarding my previous post, quickbms 0.8.5 on macosx will be built with openssl support so just wait :)

Well Hello,
they changed again the AES key for Fortnite 4.3
Do any of you guys know what one is it?
And can someone explain to me how to find it in order to do it myself in the future?
thanks

I was wondering if anyone had the encryption key for the Chinese TPS Global Mission.

It use to be a game called ZMR on Steam.

Some EXE's

So you want me to post a whole new unreal engine 3 thread? Because it's one number less?

You also do realize that the BMS script for Unreal Engine 4 that is posted here, works for unreal engine 3 right?

@GoodConduct
my script is for the PAK archives of UE4 only.
That game you have there uses an older version of the engine (upk indeed is old) and, most important, it uses a custom encryption that apparently covers only the first 0x100 bytes from offset 0x10, therefore it requires a new topic specific for that game (not UE3 in general because that's nothing related to UE3 encryptions)

Gotcha, gotta love custom encryption will make a new thread then I had no idea your script opens the PAK archives only. You learn something new everyday :)

Edit: Also to add, when it comes to the UE4 thread is it better to post the .exe or the game files or both?

The big executable and the 2 files generated by the filecutter.bms script on the pak archive.

I had no interest in downloading 2Gb of file so I just got the first megabytes and the compression is oodle which may be the error you got since ZIP 4 was snappy or lz4 in other pak archives.
So make a screenshot of quickbms when it gives you the error.
Then what's the name of the game?

tried to extract Farpoint ps4 PAK files.

script works fine, but loses 14% of the files:
Code:
- 10265 files found in 446 seconds
  coverage file 0    86%   22052930264 25457853478 . offset 00000005ed6803fa
and umodel says:
Code:
Pak F:\farpoint_vr_ps4\A0100\Image0\refuge\content\paks/pakchunk0-ps4.pak: 10265 files
Found 17412 game files (0 skipped)
is that okay? 86% is okay? will I lose some files?
