Hey all. I'm still working on my final project and have run into a little snag. Keep in mind that I am by no means a rigging expert, so my skeleton set up may be a bit off, but it works so I'll deal. Anyway, I ran into a problem when I tried to create a character placement control.

The problem is the Spline IK Handle I have in the spine of the dinosaur moves more than it should. Is this a "freezing transformations" problem, or something that can be fixed by parenting it to something. The spheres along the spine are the controls for the clusters on the spline curve, if that helps at all. Ideally, I'd like it to be positioned, keeping the controllers relative to the geometry. Thanks for any and all:)

Unparent your splineIK spline from anything, because if you have both parenting and clusters, it will be given translation x 2, which you dont want. So just do an unparent at the curve and you'll be good to go.

Edit: The clusters must be from start to the end too, every CV must have a cluster, even the beginning, or the unparenting wont do the trick.

Ahh, blast...double transformations...how could I have so BLIND!! I ended up just unparenting the spheres altogether and limiting the amount that the dinosaur would actually move on frame. But I definitely appreiciate the tip!
