I feel like this and the other thread contain a lot of answers, to different situations, and could use more clarity – old or not, still relevant.
For me specifically, for strafing movement with a blendspace
turning off Orient Rotation to Movement is what I was missing.
Because… that is continuously trying to turn the character around when moving backwards, while Use Controller Rotation Yaw is turning it forward (direction of controller) for strafing. So it is cluttering movement in other directions as well.
Wrap input on the blendspace horizontal cleans up the feet a little but the stutter specifically was the above.
