so i downloaded a pack from Mixamo in that pack are some animations for sword and shield. When i addded those animations on my character and hit play, i started walking a little and than it teleported me back a few staps and i startded walking trought walls and my camera didnt follow quite good.
See if there is an option for “in place” in maixamo. tick that and it will play it smoothly 
Thanks XxxPranavxxx, it worked
