[SOLVED BY ME] Blender Animations Plugin Not Animating Weapons?

I'm trying to animate a gun using the blender editor, and even though the gun is animated fine in blender in Studio it doesn't animate the gun. I used the Constraint Editor and made sure I made a Motor6D of the gun inside of the hand.

I used this video for reference: https://www.youtube.com/watch?v=yZAAK7MkERM&t=191s

I did everything he told me to do and no success. Am I missing something? Or is it a bug?

SOLVED: The part was anchored.

lmao
