Beug with character animation (parasite movement)

I have a problem with an animation on my 3d character. A parasite movement. I searched the origin of this problem, but I found nothing about that… I give you a short video of my beug. Is somebody able to help me ? Does it exist a solution to cancel this problem ? HELP ME PLEASE !!! :stuck_out_tongue:

I would try to enable Root Transform Position(Y) - Bake into position in model import settings, animations…if it wont help, adjusting offset should.

Thanks for your answer Bekkk, but there is no animation when I import my character into Unity… I apply the animation directly into Unity… so I haven’t theses options on my character FBX…
