I just downloaded UE4 and every time i try to start a project, my games camera just starts spinning upward and to the left. I’ve tried different project types (FPS, third-person, racing, 2D side scroller) and they all have this issue.
You have a joystick / controller plugged in and it’s drifting. That’s the issue in 99% of the cases. Do tell if that’s not it, though!
