MultiParentConstraint

  • Blends between multiple parent influences
  • Separates position and rotation weighting
  • Maintains source object references
  • Useful for hand grips or dynamic attachments

MultiReferentialConstraint

  • Maintains relationships between reference objects
  • Switches between reference coordinate systems
