Copy Rotation Constraint
The Copy Rotation constraint forces its owner to match the rotation of its target.
Options
Target
Data ID used to select the constraints target, and is not functional (red state) when it has none. See common constraint properties for more information.
Order
Allows specifying which Euler order to use during the copy operation. Defaults to the order of the owner.
Axis
These buttons control which axes are constrained.
Invert
Invert their respective corresponding axis coordinates.
Mix
Specifies how the new rotation is combined with the existing rotation.
Replace
The new axis values replace existing values.
Add
The new axis values are added to the existing values.
Before Original
The new rotation is added before the existing rotation, as if it was applied to a parent of the constraint owner.
After Original
The new rotation is added after the existing rotation, as if it was applied to a child of the constraint owner.
Offset (Legacy)
This replicates the behavior of the original Offset checkbox. It was intended to be similar to the Before Original behavior, but does not work correctly with multiple axis rotations, and is thus deprecated.
Target/Owner
Standard conversion between spaces. See common constraint properties for more information.
Influence
Controls the percentage of affect the constraint has on the object. See common constraint properties for more information.
