Some people trying to feed Chromium (yes, browser's) pak files to umodel, and then say "hey, it's unknown format". If you're CORRECTLY supplying this game's pak files, and umodel can't accept them, then right, pak files were changes and won't open. I'm not doing anything for any PUBG version, so please - don't spam with support requests (I already removed another thread you started). There's enough information about HOW to open game files, I think even on this forum.

@Yeasir: It's worth to read this topic from the start, because solution is in second post, literally.

Hey great god @spiritovod can you please help me in getting new AES key for PUBG Mobile. After latest 1.1 update old BMS scripts don't work.

I've updated my post here to reflect current situation. If some decryption routine will be posted elsewhere, I'll add it to the script, but I'm not going to dig into protected libraries by myself. For now use previous versions of the game for researches.

Thanks for your valuable reply.

I am also trying to find new AES key. But if it's possible for you can you give me Old AES key ? ( cannot find on forums )  I see the encryption is not complely changed only some parts have been modified. If you can help me in any way I shall be very thankful to you.

Previous versions are not encrypted in any way, except some stuff is xored with single byte here and there. It has nothing to do with actual AES encryption or anything like that which they started to use for the index. Considering that I was never able to find known key in the desktop version (not that I really tried), doubt that something will change for the mobile version.

Nothing about the key yet? I've managed to get the .pak from the 1.1 after hours trying to do it :'(. Well, I've learned something at least.

RIP

pubg studio released a new game (pubg new state) using ue4.26 a few days ago. fortunately spiritovod provides a script to export game files. When I use ueviewer, I found that all assets other than skeleton mesh can be viewed normally, but an Error occurs when opening the skeleton mesh.
Would you like to help me solve this problem, thank you
call stack:
Code:
FFileReader::Serialize: File=SK_Body_01_M.uexp <-
TArray::SerializeSimple <-
FStaticLODModel4::SerializeRenderItem <-
TArray::Serialize: 0/3 <-
USkeletalMesh4::Serialize <-
LoadObject: SkeletalMesh4'SK_Body_01_M.SK_Body_01_M', pos=363C, ver=522/0 (unversioned), game=ue4.26 <-
UObject::EndLoad <-
LoadWholePackage: SK_Body_01_M.uasset <-
CUmodelApp::ShowPackageUI <-
Main: umodel_build=1556

@coherence: It's usual thing for all recent mobile games on UE4, simply use specific umodel build for skeletal meshes.

@nanakjaggi: If something doesn't work in PUBG, it can't be helped. In versions below 1.1 most things should work fine, except some textures. On the screenshot you're trying to open an asset with unsupported data (it's not a mesh or texture, etc). Either way, you didn't provide any samples.

@nanakjaggi: You're also ignoring people and not providing samples. Without samples I can only suggest to try modified build for desktop version from the game topic.

Here is specific umodel build for static meshes (link) - no special override is required, simply choose proper engine version (4.18).

P.S. I already saw that scheme before in a different game. They've included sections info into bulk files, while it's expected that bulk data exists only in 4.23+ and that combination is janked by design.

@nanakjaggi: If I remember correctly, all res_minerva paks are actually encrypted even in early versions (maybe except very first release of the game). The only script which works with such archives is the one for raw extraction, available here in custom scripts bundle.
As for textures, it's most likely custom materials, which can be re-created only in a third-party software. You can get material properties in separate txt file after exporting meshes and also in the viewer itself by pressing "M" and navigating though them.

@nanakjaggi: Material is not always a simple texture: https://docs.unrealengine.com/4.26/en-US/RenderingAndGraphics/Materials/
