I looking for source code to build it with umodel viewer source, because his tool support many games on Unreal Engine 3, expecially classes of package and specific engine version, license.
Umodel allow to view and export this cooked data so there’s a possiblity to load upk in editor from released games and edit some class, SkeletalMesh then use it to game.
So summaring I want modding a non-moddable games in other way and for now I trying to compile it without edit source, to check if this non-authorized solution is working.
