Got an error during extracting Redout .pak archive:
Access violation at address 3737002A. Read of address FFFFFFFF.

Use my script:

I was looking into using alugi's script for GoW 4 since it runs on UE4 and tried looking for AES key a memory dump. It dumped a bunch of HEX strings so I'm wondering, do I need to convert them to strings to test them or am I going down completely the wrong path?

Here is what I got http://pastebin.com/55KVSR4X

[aluigi]

Upload the filecutted archive:
http://aluigi.org/bms/filecutter.bms

(the tool he used for that paste is findaes)

[BR3TON]

Heres the file cutter

[aluigi]

That one is NOT an UE4 archive.
I don't know if already exists a script for that format.
Do the following, open filecutter.bms with notepad and replace
math MEGABYTES = 2
with
math MEGABYTES = 16
Then upload the 2 bigger files it creates and give us the link.

[BR3TON]

Won't seem to let me upload the bigger files here so heres a link to them on MEGA: https://mega.nz/#!1k4ExCLK!*SPAM* ... VWyuW8Bibg

[aluigi]

What a messy format, I'm not even sure that the data at the end of the archive is a TOC with information about the archived files.
In my opinion that one is just a raw container and probably there is an index file somewhere else.

Im new, if there is a download like where in the holy *SPAM* is it?

Hi, I registered just to ask for help.

I'm using the UE4PakUnpacker v5.0 by Haoose but I have two problems.

First of all, I have no idea where the unpacked files are. If they are supposed to be in the same folder as the .pak file itself, then they are not there.

Second, when I try to unpack the file Hatred-WindowsNoEditor.pak, I get this error near the end: "Access violation at address 00006B61. Read of address 00006B61".

Really don't know how to get this to work. Any help appreciated.

UPDATE: Nevermind, I got it to work.

Hi, really thanks for this tool, it's amazing.
I tried to use it on vanishing of ethan carter but I didn't have success.
It generates the .uproject files, but didn't had success opening the project with their engine version (4.8.0), the project has uassets but the ue4 editor doesn't show them.
So i used prompt command:

C:\XXX_ENGINE_PATH\EDITOR.EXE_XXX "XXX_PROJECT_PATH\ETHAN_CARTER.uproject" -run=resavepackages -FixupLegacySetting -IgnoreVerCheck -IgnoreChangelist

to resave everything with my engine version . This gave me a LICENSEE_VERSION error. So I changed some lines in C++ editor code to match the ethan carter assets version number, and restarted the previous cmd command.
In the end I got another error, which says me that assets are saved with another engine version.
Anyone knows how could I convert uassets to another engine version and open them?

You can download older versions of the engine, im pretty sure.

Tekken 7 is an Unreal Engine 4 game but .pak files are encrypted. Is it possible to update the script to work with Tekken 7? I'll share files if needed but I'm not sure what you'd need to figure out the encryption key. Would running filecutter on the archives be enough or would you need the .exe as well? Would Denuvo mess with the process? Let me know and I'll get to uploading whatever is needed.

[aluigi]

Let's start uploading the big game executable, maybe we are lucky.

[ssringo]

I'm about to go to bed so I went ahead and uploaded the big and small exe as well as what filecutter.bms kicked out for the paks (as well as the 3rd pak since it's super small anyways). Hopefully it's enough!
