Error generate rig in (rigify) after removing tongue and bottom teeth bone when editing the human metarig, I delete bottom teeth bone and tongue bone. Because I don't need them. When I generate rig, I get error message. So I recreate the with &quot;basic.super_copy&quot;, rename, reparent and adjust their layer in relations tab. But i still get the error message and it won't generate the rig.
The error message is like this:
Generation has thrown an exception: 'bpy_prop_collection[key]: key &quot;ORG-tongue&quot; not found'
How to fix this so i can generate the rig?
Found it!
So, you create &quot;faces.super_face&quot; in rigify buttons tab.
delete all the face bone except the one that you accidentally delete. In my case, those are tongue bones and bottom teeth bone. Then, you parent them back to face bone, reposition them and click &quot;generate rig&quot; in object mode. It successfully generate the rig.
Notes for others, never delete any bones from the face rig. if you don't want to use them just deactivate &quot;deform&quot; in bones properties. *credits goes to R-800 for the info!!
