pitchipoy.super_face
The “super_face” sample rig and the “Pitchipoy Human (Meta Rig)” have some positional errors in the central bones. In effect all the heads/tails of the bones placed on the mirror line should have x=0 position and are instead created with slight different values. This will lead to some misalignments of the controls in the generated rig. After our fix the bones are now generated at correct position in both “super_face” sample rig and the “Pitchipoy Human (Meta Rig)”.

pitchipoy.super_palm
The “Pitchipoy Human (Meta Rig)” used the default “palm” rig type from original Rigify code when generating the Hand rig. Scaling non uniformly the hand control on the rig generated with this type will lead to crazy deformations on the finger bones. The problem is related to some “inherit scale” options on the parented bones. In order to leave untouched the original Rigify code we created a new rig type and named it “super_palm” using the pitchipoy naming convenction. We changed the bone parenting so that the hand can be scaled non uniformly without destroying its children bones. This new palm type is needed to append fingers and toes to the “paw” rig type.
