True First Person hand moving with walking left and right - how to freeze?

[Leaderide]

Here is a video of what I mean. When I move my character left and right, his hand moves with him. But I want to stop the hand where it is. Like how actually First Person should be, it’s very disturbing when the hand moves in front of the camera.

I guess this is what you need from my anim BP.

Thanks in advance!
