Moving bones between armatures

Hellos!

I think I did this before, but can’t remember how. I have some bones I created in one armature called armskin, because I need them snapped there. Then I need to move them to another armature, armctrl, which will drive the skinned bones. How do I do that?

I know that I can use Armature/Separate (CTRL ALT P) to take the bones out of an armature. There’s a Armature/Merge (ALT M), but it asks to “merge within chains” and seems that doesn’t do anything.

How do I move one bone from one armature to the other?

  1. separate the bone you want to move and use the Ctrl Alt P to separate the bone into its own armature object

  2. go into Object Mode and select the new armature object/bone and then shift-select the armature object you want to join to and Ctrl-P to join

But really you should not use two separate armatures in most casesm you should just join both armatures and use bone layers to keep them separate …
