Parent
This constraint makes the object behave as if the target were its parent. If you change the target's coordinates, the object will behave as if it were a child of the target in the Object manager.
Defines the overall strength of the constraint's influence on the object taking all targets in the Targets group into account.
Targets
Here you can add targets that should act as the object's parent.
Adds a new target including all appropriate settings.
Deletes the last target you added.
Drag and drop the object you want to use as the target into this field.
Controls the strength of the target's influence. This parameter is only available if two or more targets are defined. This is because if only one target is defined, its strength is controlled by the Weight value at the top of the tab. If more than one target is defined, lowering this value means the other targets will have more influence.
Here you can control whether the target affects position, scale, rotation or any combination of the three.
