Empty

An item that can be used to link items together via parent/children relationships. Empties can be animated, can be parents, and can give outputs as animations. Empties do not have physical properties of their own.

Common uses for an empty​

  1. Used as a parent for other objects to allow you to:
    • Move all the children at once
    • Organize items into groups
    • Act as an in-between to prevent scaling issues (if the empty keeps its original 1:1:1 uniform scale)
  2. It can be animated to:
    • Be used as a timer
    • Move child objects
    • Send numeric output and trigger other logic items
    • Stack animations since objects can only store one animation

Want to color your empty?​

Thanks Robin for this tip - Add a parent, like a cube. Paint the cube, and the empty will be painted as well. Then you can unparent and delete the cube.
