[Unity3D] Punishing : Gray Raven assets

Post by Kanbara » Mon Jul 27, 2020 7:16 am

Recently, this game's assets have been encrypted.
As far as I know, this game is made by unity3d (2018.4.23f1) and it is an Android mobile game.

It's 3D models and illustrations are really exquisite. I really want to rip its models from this game's assets but I came out fruitless after using AssetStudio, AssetsBundleExtractor, disunity etc..
I do hope someone nice can help me figure this out!! :D
Thanks!!

And here are some samples from this game (2MB)

Use this quickbms script batch process all assets.then AssetStudio will recognize them.

Code: Select all

get ArcName filename
set Name string "new\\"
string Name + ArcName
get Size asize
math Size - 0x04
log Name 0x04 Size

Thanks for your effort!
But it doesn't work on my part.
I think this script you made is mainly for this game's previous version. I know we can simply delete the "Kuro" before the "UnityFS" before.However, the latest version of this game has changed it encryption way and I totally got no clue of if :(
and it seems quite complicated to decrypt since it's data is irregular and messing around.
Anyway, heartfeltly thanks for your replies! :D

The latest version I installed from taptap today was not encrypted.
It's neither a kuro header nor another encryption. It was a regular unity3d file.

By the way, the second-type encryption method seems to be same in "castlevania moonlight rhapsody".
Add 70 bytes of dummy data and rewrite random bytes. I have no idea on how it will be decrypted.
Reverse animation file is a genius's job. However, animation tracing can be done by anyone with time and patience.

Yeah, I've asked some people specialized in decrypting Unity3d assets but they gave the same answer as yours--dummy and random bytes added.
But glad to know the game from taptap isn't encrypted and do hope that this game could be popular in the world! It's really a good game and the characters' skins as well as 2D portraits are fabulous :]

Up!
I wish someone could see this thread and it seems that there are some people have managed to extract the assets from this game already :constipated:

I've just tested it on version 1.9.1 of the game and all assets are unencrypted.
If you'll just remove "Kuro" word which is right before "UnityFS" signature, all files will be readable in Asset Studio or UnityEx.

But is the v1.9.1 the newest one? If not, then please specify which version of the game is encrypted.
Becasue on the google play site you can see that v1.9.1 is the newest, so I'm a little confused with your request.

The global version hasn't been encrypted yet. That's because kuro just simply "copy paste" the files that they used in the CN server.

[The following may contain spoilers]
And they didn't set complex encryption until the "Granblue version"(Swimsuit version). So before that ver, all files were able to be loaded in AssetStudio.

Ok, sure, can you tell me how can I get this "Granblue version" (or newer) to see encrypted assets?

Ok, thanks, this version for China you linked is v1.22.1, so I should see some differences now.
I'll try to check it.
