No point in trying to use them for the UPK packer, like i said before:
You can't repack the files.
First of all the Texture2D from UDK is TGA while the one in the UPK Packer is "incomplete" and compressed Texture2D file.
And second. It's not cause of the "Security" to make sure it can't be mod'ed, but cause how the Unreal Engine works.
Even you found a way to repack it so would you still unable to change any files cause you don't have the "compress/decompress-coder" to recive or update the streamkeys, hexkey data and series numbers, even by changing the alpha channel in the texture is enought to make the GPK corrupt, cause you added extra data that you didn't update add to the "list"
If you read the README so does it even say that the UPK packer doesn't even support Add or removing of file.
It is thanks to this feature of insane compression and handling of the files that we are being able to run this game in max graphic.
Without this feature so would we have 5 FPS even at medium graphics.
It is not like all other non-Unreal Engine games where you can just exract and repack the files without any problems.
There are a few p-servers appearing,I don't post any of them here.But I wonder if the "Keys" you mentioned works in those servers.
Here is a sussessful .gpk texture2d mod example

I looked some .texture2d extracted from Tera,They're different.however this article let me know the basic structure of .texture2d.Is there anyone has idea how much "lists" related to the .texture2d if we modded one of them?
It's very troublesome to mod SkeletalMesh from the articles i read in umodel forum.You mentioned the upk packer is "incomplete",,and the SkeletalMesh it extracted seems still encrypted or compressed in hexeditor,I can't find readable header.Is there any resource to read about the structure of Tera's .SkeletalMesh format?thx!
Really hope we can find a way to modify SkeletalMesh and texture2d without using Umod.
