@noob
I have just updated the UE4 script to version 0.4.21a for correcting the endian guessing.
Please remember to use this topic for UE4-related stuff.

Quick look: It's bunch of zlibed files merged into one archive. On it's very end I saw some filenames, so maybe there is TOC. (so nothing like UE4 pak file)

Qnoops wrote:@nextworld thank you for your answer, appreciated

uh-oh, I sent you to a kinda, crap video, he talks really slow, and I was unable to get his 'solution' to work (after going over the video like 4 time, EXCRUCIATING with such a slow talker, .awful video, sorry I recommended it,. :)

If you ever figure out how to do a successful mod PLEASE SHARE THE MAGIC! I am literally just trying to adapt one abandon-ware app for my nieces and nephews to learn from. Not make a career of it :) Been half a year of one long useless tutorial after another, HUNDREDS maybe THOUSANDS of wasted hours. If I was young... I would be 'triggered' instead of just beyond depressed and crushed,.. It is a simple, un-encrypted Unreal 4.18 app. I can unpak, redo chatacter rgging, anything, everything, except: get it to RUN after modding.
I don't even need to pepak!! Even still, when I try to re run after replacing a cooked asset, I get this error:

'c:/users/Woody/AppData/Local/Stage9/Saved/Config/WindowsNoEditor' must exist and contain a DefaultEngine.ini'

and even though I triple check there is a Folder called 'WindowsNoEditor' in the right place (assuming it is asking for a folder?) and an ini called:
DefaultEngine.ini, still I am never able to make even the slightest change!

Help would be so very most welcome!

Could somebody explain how to run unpacked files?

The game I'm trying to modify is Dakar 18, which was done with Unreal 4.19.
Unpacking works fine, but, due to some files being chunked, I can't really re-pack them anymore.

So I tried running with unpacked files, but not having much luck. All three PAKs the game is coming with are unpacked (and removed), and their content moved into their appropriate folders. But when i try to start the game an error comes up right away, that the game has crashed with a fatal error. No further information is given.

Moved in the correct topic.

It's a normal UE4 archive protected by password.
Once you have the key you can extract everything.
quickbms clearly tells you that you need the key.

The reason is explained here or in the reimport2 topic: the header with the offset of the TOC is located at the end of the archive, therefore it's not possible to append new files after it.

QuickBMS 0.9.1 will use a work-around in reimport2 for bypassing the problem.

I don't know if there is any public "packer" and if it's compatible with your game.

I have a little problem. I didn't find much solution about Batman Return to Arkham.
Files from a PS4 game. Unfortunately not exported.

I share a few small examples. I think you have meshes.

I tested it with unreal_tournament_4 script 0.4.20a / 0.4.21a

The samples you provided are UE3 supported by Gildor's tools.
My script is for UE4 PAK archives.
