I am having a problem parenting an object that I copied.
For example, I can place a point on the first frame of an animation. If I copy the point to all frames and then parent it to a bone in the first frame, the point will be moved to a strange location in the following frames (see attached picture). In my example I parent the point to the chest of the character in the walk_forward animation. The point is moved to under the character in the second keyframe (and all following frames).
If I parent the point to the bone, and then copy it to all frames, the result is normal.
