Note that while Gotham Knights is using 4.25 Plus engine, they've updated package format to latest one, therefore you need to use 4.27 quickbms script for assets extraction.

----------------------------------------------------------------

AES finder is updated in the base post to version 0.9g. Additional check should help in rare cases like Gotham Knights, but finder will now work longer for games without encryption because of additional extended check.

@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.

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

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

@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.

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.

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

Image

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
Image
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!

@lew2610: All UE scripts are not valid for reimport mode due to their complexity, you need to use other tools like native unrealpak to create packages. There are some useful links about it at the bottom of my base post from signature, but in general modding is out of scope of this topic.

Script for extracting assets from Ash Echoes / Fraxinus Decay is added to specific scripts bundle, available via my signature. Despite the game is on UE4, it's using proprietary packages format, which is modified version of format from GuJian series, created by the same devs. You can use the script on any file in the folder with "data" files, it should work.

About Fortnite, i can extract a normal pak file (which use 1 AES key) but when i want to re-import it says file is not same size (but in reality it is), uncompressed size is same but next to uncompressed size there is a different file size, why this is happening ?
Re-import 2 and 3 don't show this error but it change file size.
