Character holding an object I'm trying to get a character (robot) to catch a vinyl record. I have both objected linked into a blend file. I tried to use a Child of constraint on the vinyl record and parent it to the thumb bone of the character. It's moving, but it's not following the thumb. In fact it appears like it's going in the opposite direction. below are a couple of screen caps to show my issue



I'm thinking that some how the bone axes and the object axes are not aligned. So it's not following it properly? But I'm not sure and don't know how to go about fixing that.

Any help would be much appreciated.
I think I figured it out. when I add the childof constraint I was picking the armature object. But when I used the picker took and pointed it at the armature of the robot, it showed a different object; the proxy. Once I selected that, things worked as I expected.
