I know how to mod files with rez hacker.

Nexon files>Lithtech files>
But is it possiable for me to change lithtech files to .blend files or unity3d files?

Im working on a combat arms single player game. But i dont feel like doing the modeling again when i can just use there files. if its not possiable to mod these files can someone send me a download link/website link to a lithtech full download?
