Hi people today is the Genshin Impact worldwide release.
The game use Unity3D but the usual tools (UABE, AssetStudio) don't work with .blk files cause encryption.
There is an old topic viewtopic.php?f=9&t=13317 that found a solution but the game now has a more security I guess and the old decryption tool isn't working anymore. So I wanted to start a new topic wishing to find a new solution to this matter.

Unfortunately yes.
We must wait for the uncryption tool for this game.

Mysticus do you have CBT2 files? In theory those files can be decrypted with Blue efie Decryption tool.
Btw I found this web https://www.twblogs.net/a/5d11f8ecbd9eee1e5c821fba?lang=zh-cn very old but can give us hints on how is encrypted Genshin impact.

Hey, first post on this forum, I just wanted to point out that there is in fact an assets bundle on the previous thread that you linked, a Google drive link:

Please just limit yourself to provide only the requested files for analysis.
If it's a closed beta probably you are not allowed to share the whole game (not sure how it works but check by yourself).
So, jovehong, I guess it's better if you edit your links.


this closed beta needs invited account to play game
isn't it ok to share?

whatever, currently upload zip to google drive


*edit*
https://drive.google.com/drive/folders/ ... sp=sharing
2 assets .blk zip, 1 localge.pak


I already downloaded the 4GB assets zip and decrypted using this tool:

After decryption, please use AssetStudio fixed in the compressed package

I can confirm it decrypts everything without a fail but AssetStudio fail to load a lot of stuff, I am trying VERY HARD to get Amber's clothes textures and went tru almost every single file but I don't think it is there or perhaps AssetStudio is skipping it with an error, if someone can find that texture in the bundle I WOULD VERY HIGHLY GRATEFUL FOR THE REST OF MY LIFE.

Thank you so much!, I can confirm turning the Alpha channel on those "Avatar_" textures that are 1024x1024 and have nothing but a little circular icon in them, contain the whole clothing textures of characters, go to your exporting options and select BMP instead of PNG and you can save the whole thing and not just the little icon.

Thank you!

If you're like me and can't find the right faces in that mess, you can get some of the character models in .pmx (MMD) format at https://ys.biligame.com/gczj/?spm_id_fr ... 766f7465.1 (scroll down a bit)

Keep it on topic guys. We're here to talk about the decryption of the final release.

I got some friends working on it, yet will need to see if they can do it. They said it's a pretty hard encryption and safety method they are using.
