Generate Rig error: key "ORG-nose" not found' In order to generate a bone rig I have created the metarig and adjusted it to my model/character. As I am trying to create something simple (to use it in Unity), I removed the face and ears.



Then I re-calculated the noremal ("Shift + N" and then "Y").

Once I generated the rig (Object Data Properties &gt; Rigify Buttons &gt; Generate Rig) I got the following error:


  Generation has thrown an exception: 'bpy_prop_collection[key]: key
  "ORG-nose" not found'


And in the Layers it appears a new one named "rig" and it highlights the following:



What am I missing here?
Found the problem.

The face bones were not all removed as I saw one inside the big bone when I moved it.



Removing that small isolated bone solved the problem.
