It is possible to rename parts of a model while still having animations properly play on them

So in the studio i’m animating a bunch of guns that are connected to the player using motor6d’s, and I made a mistake so that two handles of the guns are named the same thing, so when the animation for gun1 plays, now gun2 simultaneously plays gun1’s animation.

The gun setup is based off of:
