I rigged some FPS hands and a gun and started make animations. I'm really struggling import my animation from Blender 2.8 to Unity.

The Animations [look fine in Blender like it should](https://www.youtube.com/watch?v=EhCWa0HXspw), but are [messed up in Unity](https://www.youtube.com/watch?v=3IUDJUUtg8E).

don't know the causes of this problem and already searched several hours for a solution.

Changing the compression of the animation in Unity makes this problem less bad, but its still noticeable and for sure not a proper solution.

If you need more info about the project settings just let me know.
