Ah, crap, I forgot about the otherActor lines. They'll need to be changed too, yup. How are your AddChild lines? Are they: addChild head:1 BODY:1 addChild notneck:1 head:1 addChild notchest:1 notneck:1 If that doesn't do it, you may have to rearrange the parameter sections so that head is before notneck, and notneck is before notchest.
