All i found was related to older versions of Blender. So the old way ‘Ctrl+Alt+P’ doesn’t semms to work anymore.
The problem i have is a rigify rig where i attached a custom facial rig (Ctrl+J). Now i need to tweak some positions of the finger rig. So i tweaked the old metarig and re-generate the rig, but the facial rig gets overwritten and dissapears.
How can i split an armature in two?
