How can I stop the mesh from stretching when posing? I'm trying to rig a model starting from a rigify metarig and it's been going pretty well. It looks like, though, the mesh is morphed and stretched everytime i pose it, which is a problem mainly for the head and hands. Is there a way to make these parts rotate while keeping their shape and size? Am I doing something wrong? (probably but still)
Apply the scale on your armature.


Select the armature and go to Object Mode.
Press &#9096; CtrlA > Apply Scale.
