How to keep anims after changing part name?

Uhh so I’m making a viewmodel for a fps game and i wanted to add shirts so i changed the arms names and now the anims are broken :frowning: is there any way i can keep the animation?

assuming the animation was done using a r15 rig and the roblox animator.
Why would you need to rename the arms??? If its an r15 or an r6 rig, the names of the parts do have to stay the same.

Could you provide more information on why you had to change the names of the arms to add clothing? That part doesnt make the most sense to me.
