Not bad AT ALL for a first model dude ... nice job indeed
placing footlker001 utp inside Override will, unfortunately; affect all the footlker001 lockers and containers throughout all the game (there are 16 or 17).
you could place it in one of the republic soldiers corpses of the Endar Spire (although only one is not repeated in-game, the rsldcrps002.utp) or add it to one of Taris' merchants to buy it later (also, other mods do add items/weapons or stuff to those corpses I recall, don't ask which mods right now however ...)
or just cheat it ... lots of cheaters out there ...
keep it up
