BLENDER RIGIFY ERROR (Generation has thrown an exception: 'bpy_prop_collection[key]: key "ear.L.004" not found') I'm trying to rig a character for a project of mine. I've never rigged in Blender before, only 3DSMax. I'm using rigify Add&gt;Armature&gt;Human (Meta-Rig) and all I've done is replace the bones to different locations and tried to generate a rig. I've gotten a few errors I've tackled so far, but currently an error I have no been able to hurdle tells me this when I try to generate &quot;Generation has thrown an exception: 'bpy_prop_collection[key]: key &quot;ear.L.004&quot; not found'&quot;
I have moved the ears outside of the head because the head of this model is a bird with a mullet. I do not need ear bones but have found that rigify humans do not generate rigs if all of the facial bones are not present as they were spawned. I plan to delete them once the rig is created.
So all that said, why is my rig not generating? And what do I need to change to make it function?
Here are my pictures of the model/problem:

I'd upload the .blend if I knew how. Please help, greatly appreciated :)
I saw your file. The ear bone is there but it was not un-parented from the other bones for some reason
You have to parent

ear.L.004 to ear.L.003
ear.R.004 to ear.R.003

Parent with Connected.
Also your metarig has Scale that has not been applied so most likely you'll have to press CTRL+A &gt; Scale (in Object Mode!)
