Copy Rotation


This constraint copies the rotation of the target. As simple as that. It can be an object or a bone. As you can see in the example, only the rotation gets copied.

The Constraint Panel



 * You have 3 buttons to select which axis get copied over.

Where To Use It
Can be used with Copy Location to fake parent relationship. As you can key the influence you can make a character pick something up and hold it in his hands.

You can also use this to align a plane with a 2D effect on it to the camera at all times. This works better than pointing it at the camera in some cases, such as a ring of atmospheric halo around a planet, where you don't want it disappear behind the planet.
