Nosgoth *.upk files

[rdlady]

I would like to request a bms script for extracting Nosgoth game assets.

Nosgoth (http://www.nosgoth.com/) was a multiplayer game by Psyonix and Square-Enix
This game was developed using Unreal engine 3. Unfortunately, the game got canceled last year.
Since the game was cancelled I have been working on a fan game based on Nosgoth.

It would be great if I could have access to the 3D models, animations, and audio of the game, to use them as reference for the new fan game.
I extracted a few 3D models from the game using ninjaripper before the game was cancelled, but when the game got cancelled I couldn't use ninjaripper anymore because the game launcher just wont open the game anymore. I extracted mostly characters from the game, but I need models and textures from the maps to use them as example for a new fan game.

The game files are in *.upk format, but it's a different type of upk format, since Umodel is not able to extract them: http://www.gildor.org/smf/index.php?topic=2217.0
You can still find the game for download on Steam.
Here is an example of Nosgoth's upk file: https://www.mediafire.com/?5flbm1iv1kem5gv
And another example is here, with the game executable: http://i-zed.net/u/Nosgoth.rar

It would be great if anyone can help making the script for decrypting/extracting Nosgoth assets, specially 3D models of buildings and character animations.
Thanks!

I was trying to follow some tutorials on how to create my own quickBMS script to extract these upk files from Nosgoth, but I got stuck right at the beginning when I used an hex viewer to try to discover the upk content format and just a bunch of invalid characters showed up at the begining of the file, like !#$^%
Any news on this topic?

Here is my progress so far, using offzip I was able to identify the offset list of the upk file:

- open input file: BCMPGame\CookedPCConsole\Armor_WingedVampire_Evolved_ARC_SF.upk
- zip data to check: 32 bytes
- zip windowBits: 15
- seek offset: 0x00000000 (0)

After that I tried to perform the extraction of that file using offzip but a bunch of dat files, a txt file, and an xxx file was created, and now I have no idea what to do with those files other then checking them in the hex editor (I did that but didn't find any clue).

I was able to decrypt the upk files and extract them using umodel/ueviewer. But the animations (psa extracted) are all wrong, the left side of the model gets distorted for some reason.
Here is one of the decrypted upk files that I opened in Gildor's program and looked all distorted.

I'm also interested in this game.
Can you tell me how exactly was this file decrypted?

[Delutto]

Use UModel.

[lolwatt]

Use UModel.

I would, but the point of this thread is that the packages are encrypted or whatever, so I cannot use UModel.
It will always throw errors at me, no matter the settings.

Ask for for help on Gildor's forum.

Yeah, I know what was discussed there. There is nothing to ask.

My question was targeted to rdlady or someone who knows how the files were decrypted...
