Sleeve isn't being weighted correctly when parenting to rig I have a model that has an arm with a short sleeve on it.  At the moment, the clothing and body are all part of the same mesh (the attached images are using a simplified version of my setup).
I'm trying to rig my character using rigify.  After generating the rig, I parent my mesh to the new rig by pressing Ctrl-P and select Armature Deform with Automatic Weights.  While this does bind the arm part of my model correctly, it does not seem to affect the sleeve.
How do I bind my sleeve?
I figured out a solution.  By adding some extra control bones specifically for the sleeve, I was able to get it to bind with useful weights.
