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.
(same animation applied to both handles)

Trying to rename the handles means the animator (using moon animator and studio default) cant recognize this new part name, and I cant fix it without redrawing the entire animation

Any ideas on how to rename a part and still have an animation recognize the new name and play correctly?

The closest solution to this problem is this plugin, but im having issues installing it so thats out of the way…
