Mapping Parent/Child constraints to one another

The Mapping constraint lets you map one Parent/Child relation to another Parent/Child relation. You can use it to scale movement between limbs or other structures of different sizes.

To map Parent/Child constraints to one another:

  1. Select a Mapping constraint from the Asset browser’s Constraints folder and drag it into the Viewer window.
    • If you drag it into an empty area of the Viewer window, the Mapping constraint template appears in the Constraint settings.
    • If you drag the constraint on top of an object, a context menu appears asking if you want to assign the object as either the Source (parent) or Constrained (child) object .

  2. Assign the object that you want to be the Child object of the Parent/Child relation that inherits translation and rotation from the source Parent/Child relation to the Constrained object (child) cell.
  3. Assign the object that you want to be the Parent object of the Parent/Child relation that inherits translation and rotation from the source Parent/Child relation to the Reference (parent) cell.
  4. Assign the object that you want to be the Child object of the Parent/Child relation that sends translation and rotation information to the constrained Parent/Child relation to the Source object (child) cell.
  5. Assign the object that you want to be the Parent object of the Parent/Child relation that sends translation and rotation information to the constrained Parent/Child relation to the Source reference (parent) cell.
  6. Click Lock in the Constraint settings to lock the position of the objects to be constrained.
  7. Click Active to activate the constraint.
