Bodyposition Moving Parts Explanations

I am unsure of why some of my moving parts don’t play the moving animation. I only know these reasons: (which are all not applicable)
Moving part cannot be anchored
There cannot be an anchored Collidable Part in the middle of the animation

To add on, the part I am moving is a union. Do union parts not work with body position?

I used wait() and part.BodyPosition

You could try increasing the Power or MaxForce, unless you’ve done so already.

Thank you! i set the max force to inf,inf,inf.
