UE 4 *.PAK File

Post by Ehnoah »

Hey,

got a Pak File I can't extract with Common tools, here is a Snippet.


See Below


Hope you can help me unpack it, I tried different Unpack Tools yet, but no chance.

At some point, it say Files are encrypted, some he unpack.

So when you use my script http://aluigi.org/bms/unreal_tournament_4.bms it asks you to insert the password, right?
In that case I need the big game executable

Binary is ~111 MB super huge. I attached:

- Binary
- 10 MB Cut (instead of 2 MB)
- Sig File (if needed)

Your Script only extract 000000000a / b / c /d etc. files. Instead of File Structure / Pathes etc. however, the Path is in the PAK from what I see in the snipped Files.

I expected stuff like: /Engine/EngineMeshes/Humanoid etc.



After File:

0000000002d00035 2926 0000000000001ce2.dat
0000000002d01035 7728 0000000000001ce3.dat
0000000002d03035 774 0000000000001ce4.dat
0000000002d03835 9453 0000000000001ce5.dat
0000000002d06035 4566052 0000000000001ce6.dat

He say:

It looks like the TOC at offset 0x1c0766abf (0x707593 in the second sample) is encrypted.
Currently I don't plan to support custom archives.
