So I have an arm model that is children of a container, and this container is in my player. My problem is: in game, the arm model is very slowly going down, and when im moving, the arm model goes down faster!!!
My arm model has only an animation attached to it… I use Umotion for animation.
Those are some screenshots:

OK, I have found the solution!
For those who are interested, just uncheck apply root motion. It was making my animation move independently.
