ALTAVA - Unpacking an unknown Unity asset file

[vchakchina]

Hello. I need help with unpacking one unity asset file. Neither AssetsStudio nor AssetsRipper can open this and similar files. It is probably encrypted, but I have little experience with this, I hope for your help. Thanks

The game is called ALTAVA, it is a new mobile game from a Korean company. Here is a link to the game itself: https://apkcombo.com/altava-fashion-avatar-chat/com.umr.altava/
Some assets can be found in the APK file itself without installing the game

This tool allowed me to view the contents of the __data file and repackage this file into a RESS file, but neither AssetsStudio nor AssetsRipper still work with these files. Maybe I'm doing something wrong? But this thing looks useful, thanks for sharing

File -> Open, Select __data, Click Memory, Click Info, Select Texture2D, Click Plugins and Export Texture

Yeah, that's what I did.  But is there a way to export the mesh?
