Just dont want to attract too much attention with this as of now..
So please PM me if you think you can help, we are hitting some serious walls.

Dont worry, we'll let all of you know when we get a breakthrough !

I tried opening the block_export folder in the custom AssetStudio, but it's not loading files for me either

Am I missing a step/file?
(I have the asset_index in the folder with it, it just doesn't show in the assetstudio open file section)

Can someone upload the asset_index file? It looks like without the asset_index i cant convert *.blk files
Ive already downloaded the 4gb blocks zip https://drive.google.com/file/d/1enr71VmvnG9pGxd3g42FfnIcskJnVtX9
And I hope that the files in that zip are files from CB2 that the decryption tool will work with

If you read the description right above the link and don't understand what it means, it's not for you.

Is this asset_index file the same version as this resource file?
When I use AssetStudio to open the decrypted resource file, it says No file was loaded.
Could this also be a problem with AssetStudio?

Can anyone share the 25060239.blk and 33067900.blk in Genshin Impact's closed beta 3 with me?.I don't have them. They are very important to fix upskirt censorship of 1.1.

Hi, Can anyone share whole 4.7gb block files again please? No one links is available. I tried to decrypt the actual files of the current PC version. But I failed. They used a kernel-based anti-cheat system that interrupts any process trying to attach to game process.
