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

[Uwuton]

anyone know if theres a script that lets you add more than one aes key when extracting?

[spiritovod]

@Uwuton: The only known game with multiple keys is Fortnite, which is not supported by quickbms scripts anyway. And the finder from my signature is producing only one key (if any). Therefore there is no need for such feature.

I am trying to extract the files for FF 7 Remake Intergrade and all I am getting is this: - please insert the content for the variable KEY:

PLEASE help me.

@Puterboy1: Use 4.25 script, available via my signature. Though it may not work properly for mods, but it should work with base game.

@spiritovod
Back 4 Blood got updated.
Could you please look into it and update the script?
Thanks in advance.

[spiritovod]

@Kahuna: If someone will provide sample packages from the update, I'll take a look.

@Kahuna: I've updated Back 4 Blood script in the specific scripts bundle, it should work with the update now.

@spiritovod
Thanks for the script. I just tried to unpack the game with this and the last quickbms version but the process stops at "pakchunk14-WindowsNoEditor.pak".
Below I have attached the error message along with the .pak archive.

@Kahuna: I forgot about quickbms specifics -_- It should be fixed now, just download updated script.

[Kahuna]

@spiritovod: works like a charm. Thank you

Hello. Who here has tried to extract the resources pak\ucas of "Star Trek prodigies" ?

[spiritovod]

@AhsokaTano: If you mean Star Trek Prodigy: Supernova, you can extract pak files with 4.27 script, available via my signature, or just use fmodel for both paks and io store packages (utoc/ucas). If you need only graphic assets from there (models/textures), you can use umodel. Though extracting data from utoc/ucas is usually pointless, unless it's for modding purposes and you actually know what to do with it.

I would like to extract the characters. And it looks like they are they are utoc/lucas which weighs 6gb. The search for models via Umodel did not yield results in the pak file, which is smaller.

[spiritovod]

@AhsokaTano: Both umodel and fmodel supports utoc/ucas packages and graphic assets from them. Though it's out of scope of this topic.

Also Interested in this one, I've tried with umodel with no results. I also ran some tools which gave me a few AES keys, but don't know how to test them with the UTOC/UPAK files

umodel seems to have currently issues with loading some ucas from Crisis Core (for example it doesn't load pakchunk0 from Switch version).
Create another topic for this issue as you can read in topic title - discussion is pak only.

[spiritovod]

I usually ignore umodel stuff here, because it should be discussed in respective place, but here you are:

I used Quickbms and unreal_tournament_4_0.4.27d_paks_only to unpack the file.


Img
I just edited the Game.lorce file but when I repack it, it's only >2gb from >5gb.
When I enter the game, I get an error like the picture

Img
So, is it the wrong version or did I do something wrong?
I also tried unpacking it didn't change anything and then repacking it, trying to run the game still gives me the same error!
