Unpacking the game archives (James Cameron's Avatar: The Game)
I don't know if this post is appropriate or if I should have gone to other forums... But still, people, is there any way to unpack the .PAK archives of the game?All archivers that I found were for other games (Crysis, Aion, Total War) and are unlikely to be suitable for James Cameron's Avatar: The Game. But I really need to get the models out of there, for further animation in 3D Max.
You may have to write a game unpacker on your own (and maybe even a plug-in for 3D Max itself), but unfortunately I'm not a programmer. Is there anyone here who can help?

The game was released 4 years ago, so far no one has picked it open. In the wilds of the Internet, I only found a resource unpacker. Actually, not an unpacker, but a script for quickbms.exe I don’t remember the link to the source, here is its text:

In the first line of the first script, note # Avatar: The Game (UNFINISHED, DO NOT USE!) - not ready not to use. Perhaps somewhere incorrectly unpacks.
data.pak unpacked completely. You can still figure out the textures, they are in the DDS format, although there are extra 32 bytes in the head. But the problem is with avatars and models. I'm writing a MaxScript, figured out the skeleton, the tops of the faces, but I still don't understand how the mesh is written.
Plugins and scripts for this format *.xbg did not see.
