What you uploaded isn't textures, it's the main game files to run it, which is nothing more than a CEF wrapper for a browser. Does this game have other files holding the actual textures/models or are they all hot-loaded from the web?
The main exe is wrapped with Themida (64bit), so I didn't bother digging into it more than a quick look since I don't have time to boot up my VM and mess with it personally. But from what you uploaded, it doesn't look like any of it is textures at least.
Sure mate, tha actual textures/models are storage in .big files, I can provide you some some scripts that extracting .bigs, also one for decompression. I used file cutter, so there are data 4 big, where are the textures, models and I know that they used here chunkzip compression, data 10 big used chunlzma compression, and in thai_bg I think are main database, but I know db means for database and players id. I didn't know how to extracted it. Here are bigs, and useful scripts, I used file cutter: https://www.mediafire.com/file/gvgpk0zk ... s.rar/file
