The image has an IK Hell deja vu quality about it. What happens, I think, is that the trans coordinates for the child parts are set to locations that the IK glued parent refuses to accept. My experience has been that it's generally best to turn off IK, tedious as the process is, unless you actually are using it for something. Even that isn't foolproof, because turning it back on temporarily can botch things, especially in animations. I'm hoping to see some refinements to IK in P6. It's a fabulous feature when it works, and a nightmare when it starts exhibiting a "mind" of its own. M
