Unreal Engine 4 pak-file Unpacker / unreal_tournament_4.bms [UE4 global topic]

[TheRanger]

Can anyone help me with Borderlands 3 ? A lot of pak files do not get unpacked. I have used the right decryption key and the large files get unpacked fine but a lot of them don't. Take example of pakchunk14-WindowsNoEditor.pak. Size is 10mb. If I try to unpack it this is the error I get :



I am sure the file has zlib/deflate data in it.

You can download the file from here

Seems to work fine! Thank you very much!

Now, someone can explain to me how to edit the bms script in the way that it process all pak files without asking to me for the encryption key every time?

Edti: another thing. What tool we can use to re-create the pak files after that we have extracted them ? Trying with Borderlands 3 i used an old version of UnrealPak.exe but the game doesn't work.

Hello friend,

Thank you for the script but it's still not working on the 7 .pak files

pakchunk85-WindowsNoEditor_0_P.pak
pakchunk86-WindowsNoEditor_0_P.pak
pakchunk87-WindowsNoEditor_0_P.pak
pakchunk88-WindowsNoEditor_0_P.pak
pakchunk89-WindowsNoEditor_0_P.pak
pakchunk90-WindowsNoEditor_0_P.pak
pakchunk91-WindowsNoEditor_0_P.pak

Error:
https://prnt.sc/ptgfsl

I've downloaded the script twice and I've tried on 0.10.1 and 0.10.0 just to be sure :/

I'm also running Python 2.7.17 which has been working fine with QuickBMS

I'm so close to having BL3 run with open files. I get past the Oakgame error, it begins to load, but then there are more missing files and it crashes
If we can open these last 7 files I think I can get the game to load without error and it would be open to mod!

" *.uexp is archive for data - in default it's not compressed nor encrypted, but it can be cofigured by devs if they want to modify the way how files are packed.
*.uasset has informations about files inside uexp - their filenames and references - and how big is *.uexp file:
Code:
*size in bytes*-4 converted to Hex Little Endian
f.e.
1966078-4 = FAFF1DIf you change size of *.uexp file and you don't change value inside *.uasset, game will not load "

i don't understand this part, can anyone help me with a video or website that contain tutorial about it ?

am i right using the unreal_tournament_4_0.4.23.1a.bms script for unpacking?

[Silarious]

GHFear can you find out if this game even has an encryption key? Quickbms says it does but other people say its not encrypted.

Many Thanks!

Decrypt this please (Rune II):

@JaysonPhoenix:
You can find the key on rin forums in my updated list.

@Silarious:
The Cycle's archive is not encrypted. Use latest bms script (0.4.23.1a) to unpack it.

@L0v3cr4ft:
The old key from public beta still works with full version. You can find it in that post.

[Silarious]

@spiritovod how to I find that version? I do not see where 0.4.23.1a is.
