Quick Bone Reparent
Why is Bind unavailable?
Make sure both bone fields are filled in, or select a valid mesh face. Exit Armature Edit Mode and check the error message in Link Setup.
Why does the eyedropper reject a bone?
The selected bone cannot be the child itself, its ancestor, or its descendant. Choose a different bone that won't create a dependency cycle.
Why does Bake report an error?
Check the error message and make sure NLA Tweak Mode is disabled. Some constraints, drivers, or connected bones may prevent the final pose from being reproduced using transform keyframes. If baking fails, the previous Actions are automatically restored.
Why does a baked item remain disabled?
This is expected while its baked Action is playing within the baked frame range. Switch back to the original Action to reactivate the live virtual parent.
