Hello,
I just copied exactly what the included 3rd person sample does in UE5.2.1 but whenever I turn with the mouse the character jitters. Even if I open the untouched sample from unreal it shakes too. I loaded up UE4 and checked with the old sample/old mannequin and that one doesn’t seem to have it so must be something UE5 related. I was thinking if it’s maybe the input system and how it changed from the input settings to enhanced input instead? Something is definitely fishy and if the source sample has it it’s probably something under the hood?
