My spine (Spine 4.0.56) rig has stretchy bones that follow a path. The Utility skeleton (Unity 2017) objects are following but not correctly at all (in follow mode). Animation works fine in 2017.1.0 otherwise but I would like to attach other objects in the hierarchy without using the bone follower script.

Is there a fix for this issue? I'm assuming its some sort of problem with using IK or scaling bones. I'll send you the dragon rig if you have Unity 2017.1.0p4 available.

So in play runtime mode the expected behavior for the Skeleton Utility game objects is that they exactly match the transforms of their assigned bone transforms. In the image you will see that the manipulator for the selected game object shows that the HeadCTL bone is nowhere near the head.

The actual position of the HeadCTL bone is in near the eyes inside of the spine software program that I use to animate in. I assume it is that way in unity but the Skeleton Utility script isn't reading it that way (I guess). The animation itself is working perfectly in unity so I would assume that all the deforming bones are in their correct positions inside of unity.

All skeleton utility game objects that are in the neck and head area are not following correctly either and what they have in common is that those bones are under the influence of path IK constrains and bone scaling in the actual spine rig.

To show that the bone script is in fact engaged.
