Unpacking and Decrypting [The Isle]

Post by StijnDark »

Hey y'all :mrgreen:

So i've been trying to decrypt and unpack a pak file from the game The Isle. I tried everything, searched everywhere and looked through every topic of all kinds of sites. But yet found nothing that works, im not the best at decrypting and then unpacking pak files so i hope someone here is able to help me out. I used UE Viewer and quickbms but they both only extracted the uasset and uexp files which is good, but theres more in the files than only those i think. And if you haven't noticed yet the game is build on Unreal Engine :)


Edit: .pak file:

i forgot to mention that i do have the AES code
-

And i think the Unreal Engine version should be 4.23
Atleast that's the only version i could use to open the uasset files in UE Viewer.

Basically the Engine and Game folders are full of uasset and uexp files, however Plugins and TheIsle folder are completely empty and i see no files. I see config folders and there is no single file in it. I doubt it that its meant to be empty lol.

And as i said before, QuickBMS and UE Viewer both did exactly the same. - extracting Engine and Game folders only.
