Here is script for unpacking lpk files from steam (default option) and ru versions of the game. Credits to Brouznouf for algorithm.

Update: Script is updated to properly decrypt databases from lpk files. All issues should be resolved in "fix" update.

It worked!. It’s so hard to find the model I’m looking for lmao. I managed to find a costume and a head. I’m still trying to find the missing textures .

thx for the script. i have extracted the font.lpk file successfully. have anyway to repack the files to .lpk file ?

Hello everyone!
I'm looking for a way to take language files from RU client and move them to Steam client (adding or changing any of the Steam client languages to RU).
Is there a way?
I think it's easy to do such thing to voice files, but as for the text - I just don't know what files contains language text data.
Any advice?

The text seem stored in EFGame_Extra\ClientData\TableData\EFTable_GameMsg.db, you can check it by notepad.

There's no such directory as EFGame_Extra in Steam client. Only EFGame.

Hello!

I'm new to game client hacking and I'm a little confused.

What I want to achieve: extract bitmaps (skills, maps etc), data info (skill names and props, item names and props, mob names etc) from the Lost Ark game
What I've done so far: I've downloaded and unarchived QuickBMS, downloaded the bms file on page 6 and tried the following command:

.\quickbms.exe .\scripts\lpk_extract_v2_fix.bms 'C:\Program Files (x86)\Steam\steamapps\common\Lost Ark\EFGame\ReleasePC\Packages' "C:\LostArk_packages"

The result:

QuickBMS generic files extractor and reimporter 0.11.0

- start the scanning of the input folder: C:\Program Files (x86)\Steam\steamapps\common\Lost Ark\EFGame\ReleasePC\Packages
- open input file C:\Program Files (x86)\Steam\steamapps\common\Lost Ark\EFGame\ReleasePC\Packages\.\07F8Q0K8X0JS8DCXQ6WK8XX0CM5JYDYE40.upk
- open script .\scripts\lpk_extract_v2_fix.bms
- set output folder C:\LostArk_packages
- the folder doesn't exist, do you want to create it (y/N)?:

       Can't read 934261218 bytes from offset 00000c32.
       Anyway don't worry, it's possible that the BMS script has been written
       to exit in this way if it's reached the end of the archive so check it
       or contact its author or verify that all the files have been extracted.
       Please check the following coverage information to know if it's ok.

  coverage file 0   100%   3122       3122       . offset 00000c32

Last script line before the error or that produced the error:
  15  log MEMORY_FILE 4 SIZE

- OFFSET       0x00000004
- SIZE         0x37afbe10
  coverage file 0   100%   3122       3122       . offset 00000c32

What am I doing wrong? I saw someone suggesting to use umodel, but isn't it a tool to view 3d models?

Thanks

EDIT: actually I just manually selected all the lpk files and it worked fine. Now the question is: how to read the db files? According to the header it's a standard SQLite3 file, but with 16 reserved bytes at each page, which means they're using some kind of extension (not excluded an encrypting one). Also there are no bitmaps, but "loa" and "epf" files. Do you have any clue on what they are?

you have to decrypt the lpk file.
you can find the method on page 7 in this post.

Updated script for repacking lpk is added to the original post: viewtopic.php?f=9&t=2969&p=69954#p69954

Read notes in that post for more info. It's still not tested with actual game though.
