The Rotation Constraint allows you to set limits on an object's rotation and/or copy the rotation properties from a target object. These properties can be independently activated.
Use the Constraints section of the Inspector to add a Rotation Constraint to an object.
Use the new constraint's fly-out menu to select a target for this constraint.
Manipulating the target object now causes the constrained object to copy Rotation properties.
The Strength property determines how much the constrained object is affected.
A Strength of 0% means the constraint won't have any effect.
A Strength of 50% means half the value from the target will be applied.
Choose whether this constraint should use World or Local coordinates for the Source Space.
Choose whether this constraint should use World or Local coordinates for the Destination Space.
Choose whether this constraint should use World or Local coordinates for the Min/Max Space.
Allows the constraint owner to be manually offset from the constraint source.
Define the rate at which the rotation property is copied.
Use the numerical values to define the minimum and maximum limits of the constraint.
