This sounds incredibly similar to the Skeleton Builder framework I've written. Except that Skeleton Builder manages creation of the skeleton as well as the creation of the rig. As for containers (or assets as they're now called) they're kinda cool, but have a major problem if you're going to use them for holding rig controls. Basically any transform in a container acts weirdly in the channel box. It drove the animators insane when I tried using them. Try it out and you'll soon see. They're great from rigger's perspective, but from the end user's perspective they seemed to frustrating and needlessly buggy/complicated. Heya Morgan!

I didn't catch it, but it looks like the spring solver behaves differently from the other solvers in that somehow it's getting its twist from its local space as well as the pole vector. What I'd try is to put the spring solver joint chain in a world space group, and point constrain it into your hierarchy so that it doesn't inherit rotations. I did a quick test and that seemed to work, but I'll definitely have to look into it more to make sure its stable. I wouldn't recommend trying to counter it with the twist, for the reasons you stated. For something like this, if it seems like a transformation problem, I like to try to come up with a transformation solution first. Thanks for troubleshooting that, guys! Ah, yes, that is interesting.

I understand that the node hierarchy is crucial to avoid double translations but in this case all my other IKs are working fine and the spring hind leg elements are arranged in the same way. I've implemented Jared's fix and it seems to do the trick but, from his description, there needs to be a more reliable fix for it. Cheers Heya guys,

Is it a double-transformation problem that might be solved by rearranging the hierarchy? I'll take a look at my current setup and see if I find anything weird. Like I said I haven't really put this through the paces yet. And when I find a moment I could certainly try to do a little tutorial on creating falloff with a remap value node.

However when I rotate my rig in Y. my leg joints double rotate and I can't stop em. Have tried pole vectors and the No Flip method, from Art of Rigging.. Pole Vector X 0.1 Pole Vector Y 0 Pole Vector Z 0 Then offset the Twist attribute of the solver by 90, but still no joy. I'm a bit of a noob at rigging and would appreciate an update if you figure it out. Also love to see how you hook up that feathering. Thanks for sharing.. Hey Morgan,
