Description

Creates an invisible entity that only has a position, rotation and scale. Pivots are the glue of a scene: parent other entities to one and you can move, turn or scale the whole group, or make something orbit by offsetting it from a pivot that you turn. The pivot is created at the origin, even when it has a parent.
