I think he was tinkering with it, but when it comes to doing animation with so many possible figures, and with so many different morph names, and so many different figure sizes and shapes, you just gotta clunk it out by hand.

It's amazing walk designer and universal poses make life so much easier.
Since yo ucan almost just drop those in, adding 3 or 4 total morphs to a animation sequence is already child's play.

Way too many people take way too many things way too seriously.
