The exact location will require some adjustment, as I recall. The script ties the origin of the ball to the origin of the hand, as you guessed; you'll probably have to use Display Origin and adjust the three Origin dials to make it look right. ------------- As for the backward movement: Not quite clear from your description, but it sounds like you're [ordinary]parenting a ball to the hand, then [foster]parenting another ball to the first ball? Have you tried just [foster]parenting the thrown ball to the hand? The script does work with that arrangement, but I never tried a double-parenting......
