Freecam

Detaches the camera so you can fly it around while your player stays put.

Your player stands still where you left it and is drawn in the world like anyone else. The movement keys fly the camera instead: Jump goes up, Sneak goes down, and holding Sprint doubles the speed. The mouse turns the camera, and attacking or using items still happens from your player's real position and rotation.

Freecam turns itself off when you change worlds or dimensions.
