I also thought that. But I have my doubts. Because of the file size. In both CBT3 and final release they are exactly 27,500KB and are exactly the same inside.

I wonder if they just didn't change anything from CBT3 or if they stream the table

I can tell you they did change stuff. If it was the asset_index, it shouldn't be exactly the same on both. I highly doubt the game is streaming anything related to the decryption because you can start the game offline and get to main menu, and the assets on main menu are in those blk files. So it can't be else you couldn't see that. Everything must be local, just have to find a way.

I know it loads about 3 or 4 blks outside of the resource table. Could be stored in there.

As for Unity file parsing: animations aren't the only thing that are changed in format. Game objects and renderers are broken too which are needed to correctly parse skeletons.

Which are the animation files? I don't seem to see them

They're all over the place. It'll be easier to find files once you figure out your way around.
You can do a search for the string "Ani_Avatar_Girl_RunCycle"

Then i am trying to export model with skeleton, fixed asset studio gives this error:


an object reference does not point to an instance of an object
In result, the nodes(skeleton) are only exported.
Asset studio can load the objects, but can't export them...

Can it export static meshes or is nothing working?

Also what version of the game are you using? I can't load any meshes or textures from the game. Only general unity assets

A lot of formats changed, exporting tends to not work.

Right now we're still trying to decrypt the live game so don't expect fixes.

Hard stuff..
We need to figure out the XOR encryption; thus reverse engineer the client which is, itself, protected by VMprotect..
We have a community trying its hand at it, if anyone is interested to help and join the discord.

Which Discord? I'm awful with encryption but I'm in the process of fixing AssetStudio to work with the modified CBT formats.

Even when extraction gets figured out am I safe to assume that the anti-cheat will prevent us from ever modifying the blk files? Would love to replace some textures and be able to modify meshes but I'm assuming this will never be a safe option.

Right now the game doesn't freak out when you are missing blk files, it just either freezes the renderer or crashes if it tries to load something that isn't there. I don't think modifying the game will trip up the anti cheat but it might. There were checksums in CB2 for the unity files inside of the blocks.

has anyone figued out if the object (chest etc) coords are in the files?

Nope. Intractable objects map info is not stored locally. At least not the Anemocules and Geocules, haven't checked chests yet but I assume not

Hello, may I ask if we're able to get images that show up on wish sequence such as characters and weapons?
I tried finding them online but I need them high quality. Would that method work for my favor? If not, do you have any ideas about where can I rip those from?

what a shame, else we could have made an object map like the botw one

I have a decent bit of experience bypassing hardware implemented encryption keys, but I have a lot to learn on the software front.

Definitely interested in decrypting GE client, and I can help create a clientside "server" for UDP handling.

If anyone can point me in the right direction to get a foothold on the XOR decryption, that would be great.

I am concerned that mihoyo might patch the game in a way that prevents future content updates from being accessible to an offline client (especially if this gets a significant amount of traction), but I guess we worry about that once we get there.

It says it right there "please make sure that the asset_index and blocks folders are in the same directory"

You need a file called asset_Index and it needs to be in the same folder that your blocks folder is in. Do not put it in the blocks folder

Try using an emulator like NOX to play the android version of PC

hey you thank you for replying, I meant the whole 4.7gb block Files , I searched the whole internet for them and only found the cbt2 files, if anyone wants them pm me

I think no emulator support for genshin cause 64bit requirement, even if it said 64bit version of nox,bluestack etc, cause native bridge(libhoudini) to emulate 64bit games already old and not compatible
