Yes that is correct. The movement, the mouse all of that works without issue. The problem is, when you start the TestMap, do not move the or touch the mouse once it is started and notice the camera relative rotation being printed on the screen. That does not update at all. Once you move the mouse and change directions, it begins updating. Then if you go back so you are facing a 90 degree and move just past the horizon by looking up, the camera stops updating. You can also see by pressing F, when the camera is not updating, how the camera fails to follow the character. Also when the camera is not updating, the camera does not bob. if you move the look down to where it is updating, you will see the head bob. Does that help clarify? I might need to post a small video to better see what I am experiencing.
