having all the names deobfuscated could help with the meshes that miss textures?

Hi y'all, did anyone figure out how to export your lost ark character? I'd imagine it's something along the lines of reading the customization (.cus) files and combining assets in the right places. Are character customization options common across UE or completely unique to Lost Ark? Any help is greatly appreciated!

Hi guys! I have a VK version of a game, their using another method of filenames obfuscation. Any know how to deobfuscating that? Maybe just need a different conversion table?

Example:
   Filename: 9G1MBIV4N1GZZEF4H0RG63S.upk
   Object: mn_cdkbo_00_ani_sk
   Class: SkeletalMesh

I'm uploaded a txt file which contains of all obfuscated names.
https://filebin.net/0m9xcpf33zob5wvw/LostArkNames.txt

Any chance of reupload the deobfuscated names?

Since the topic got derailed from its original purpose a way too much, all posts with unrelated to umodel issues will be removed from the topic from now on (including modding) - except for renaming utilities, which are related to umodel usage, or actual contributions. If you want to discuss those things, create a separate topic in other forum sections. Thanks for your understanding.

All things from the base post at the first page are mentioned there only for references and could be outdated. Also please don't report problems with some packages in recent game versions, it's a known issue (but thanks to all who did it already, it's actually helpful).

Hey @spiritovod, any chance of a Linux build for the Lost Ark version of UE Viewer? Looking to do some automatic static asset extraction in CI and would be a lot more straightforward/performant to have a native linux version instead of having to jump through hoops to get it running under Wine.

@molenzwiebel: It's hardly possible, because used ACL library has various issues with compilation even on Windows / MSVC (the game is using old variation from 3-4 years ago). Sorry, but I'm not going to dig into fixing the whole library for other platforms / compilers.

@spiritovod No problem, managed to work around it using Wine.

I noticed that some textures fail to extract because they're EFTexture2Ds instead of just Texture2D. Would it be possible to treat those the same? It seems that the actual contents are the same, just with some added properties for marking the texture as an atlas.

An example of a file with these is EFUI_ICONATLAS_Q.upk/QXUI2CICOHYN3YG2R2JF0CIC.upk. Here's one from the western builds: https://files.catbox.moe/uyiubl.upk.

@molenzwiebel: I've added support for EFTexture2D objects in the updated build. Though only textures can be exported from them, like with usual textures.

I've checked all latest game versions except for korean one (and japanese, because it's already out of service) and none of them are using new encryption method for packages, which was introduced in 2023. At this point I'm not sure it's still used in the kr version or if this method is aimed for packages to begin with. Though it would explain my problems with researching versions from accessible regions, because respective code is never reached at runtime there. If someone can confirm situation with current kr version, it would be really appreciated.

Considering all this, a few last pages are cleaned from confusing posts and my replies, because issues mentioned there were related to corrupted packages and incorrect usage of regions settings in specific umodel build, not to the updated encryption (to avoid checking those particular issues again in the future). Base post on the first page is also updated to reflect test results.

I tried extracting all the packages from the steam version but umodel kept crashing because of the sheer amount of files and contents so I put each file individually in a batch and found some upk files that got me some errors:
