[UE3] Lost Ark

[spiritovod]

@Icos: Took a quick look - they've added additional encryption scheme, where key is derived for every suitable package (which is determined separately) from lookup table based on certain calculations on unwrapped package name or something. I suppose my previous post is applied here as well and further research will be postponed until the change is rolled out to other regions.

I made a python script to automatically convert all db files to json: https://raw.githubusercontent.com/BarutSRB/LA_Tools/main/tojson.py

This is the list improperly extracted db files:

Has anyone been able to extract properly the above files?

Is gildor or any debugger still working on this for the recent versions? I have 2023 version of this game, and I don't know where to find a 2021 version.

you can use steamdb to download old versions of games from steam ==> Guide to Download Older Versions of a Steam Game

@Xanathar, @Barut: It was quickbms related stuff, which caused undefined behavior in some cases. It should be fixed now in the updated script, tested on steam version.

@Aurorans: Read the topic carefully, starting from this post. Currently only newest korean version has issues with proper support, other versions should work fine with specific umodel build.

Update Managed to find quickbms files, and the custom build should the inside the first page of this thread

Now   i have to understand how to deobfuscate the pack names i guess

could i ask where i can found the mount models of the game pls?

Modding should be doable, just need to unpack and repack .upk file. Unfortunately this game is very specific so none of the old tools work.

Online games can't turn off anti-cheats, so Black Desert also uses meta injectors to keep EAT from noticing that it changed files.
As a result, modding is possible if the meta injector is converted for LOSTARK.

I tried, but I felt limited with my programming skills...

Wasn't the encryption of the lost ark already undone?

There is a perfect upk edit tool, but the they says there is no support for mmo.
I'll have to find another way.

true, but a lot of models share textures, so for a lot of them the viewer can't find the proper textures, so a way to have all the proper textures, could be to extract the upk, and store the various texture in the same place, in that way loading a model, it could find also the proper texture

i don't know if there is  a smarter way to find where the specific textures are stored
