Cannot assign vertex group to eye bone in rigify rig I am new to Blender, but have worked with other 3D programs. I'm trying to rig a model in Blender 2.82 using the built-in human metarig and rigify. It's gone well so far, but I cannot weight the eye mesh to the eye bones. They simply will not move with it properly.

I have the armature modifier applied properly, as seen below...


And the vertex groups named after the appropriate bones as I understand it after further research.



The meshes are weighted 100% to the appropriate vertex groups. To my understanding this should work, but the eyes simply do not move properly. I've tried renaming the groups to other bones involved in eye movement, and tested them on their own with a different instance of this default rig, but can't get them to work.

The blend file can be found on this Blend-Exchange link, if it helps.

I'm stumped. Can anyone help with this issue? 

Thank you.
You've disabled the bone's Deform option. Also don't forget to unlock its Transform options.
