While exploring the rig, I came across an abundance of bones such as P-Bone and P-P-Bone. They are only used to parent other bones, nothing more.
I would understand if there were few such bones. Then I would think that the purpose of these bones is to organize the structure of the rig. But sometimes these bones are created even for such small things as a finger, an object of an accessory, etc. As a result, we have a bunch of these P-Bones or P-P-Bones.
How do these bones help?
