Sadly it barely works for me with the BLK files, but it works for others. Don't load all BLK files unless you have 16-32GB RAM because AssetStudio will eat your RAM's ass if you try to load all BLK files.

Does anyone know what the encryption used for ctable_streaming.dat? Same as for blk? :)

Well, i think file ctable_streaming.dat seems not used, cuz its created 2 years ago and since that time has not even changed. Also i just deleted this file from folder and game works fine.
I don't know why it is still there. Anyway, if someone interested to play with IL2Cpp for 2.0 here fixes. Have fun :)

Do you plan to update your AssetStudio script?

I did not create this AssetStudio, Khang06 created it. I just compiled it.
https://github.com/khang06/AssetStudio
Also there is a discord server trying to run offline/private server of Genshin Impact. Some has succeed with it but you have to ask "klpong" for that.
https://discord.gg/d8epbG5Fm3

If you compile Khang06 blkstuff, you can batch convert .blk files into .bin files and use it with Khang06 AssetStudio but it is REALLY slow if loading .bin files. Otherwise I couldn't be able to extract the models with their armature, only empties.

Hello. Whether this applies to blk files I don't know. I wanted to take out the 2D textures of the characters. If this has nothing to do with blk files, then tell me where can I get them without a background? (Sorry my bad english)

Hi, is there any tool to edit/pack BLK files? Because i am trying to modify the textures in the V1.5 offline game. Looking forward to your reply.

Has there been any progress on AssetStudio or BLK in general? I managed to get textures just fine but models exported to FBX get corrupted, really wanted to get the original rigging for the characters.

Is there a way to only get the Textures without getting the meshes, the memory is too much for my PC and I only need the textures.

There is a modified version of AS by Razmoth that handles miHoyo games exclusively and can be found here:

https://gitlab.com/RazTools/Studio/-/releases

you just need to choose which game you are extracting from (Genshin Impact, Honkai Impaact 3rd, Zenless Zone Zero, Honkai: Star Rail, Tears of Themis) and then open the game file(s):

Is there a Windows-ready-to-use version of the app? I mean an allready compiled version?

it's included there, in the form of 3 different compilations either using .net 4,5 or 6.
