Introducing the Spine

So in scouring the net for Examples of really good rigs I finally have started finding some really good information. So today let me focus on a cool little spine setup I ran across. Actually there are several things about David Walden’s Rig that I like, but I will focus on the Spine first.

If you take a look at the image below you will see that when the lower joints, such as the lower torso, are rotated the upper joints (like the upper torso) automatically counter rotate to give a very natural feel to the rig, at least for me. Off the top of my head I would say that this is probably done with a reverse node. Lets find out.

(Only the lower joints were rotated here, the upper joints automatically counter rotate, Rig from www.davidwalden.com)


Looking into the Hypergraph and mapping one of the spine control curves we get the following.

Well there is a reverse node as well as some orient constraints. I will pull it all apart and the next update will be details of exactly how it all works.
