Each bone created in the Skinning Editor should represent what?

In the context of the Skinning Editor within Unity, each bone created should correspond to a single bone in the rigged model. This correspondence is crucial for ensuring that the skinning process works correctly; each vertex in the model can be assigned to influence from one or more bones. By establishing this one-to-one relationship, animators can better control how the mesh deforms during animations, leading to more realistic movements and expressions in character animation.

The proper mapping of bones also aids in achieving a clean hierarchy in the rig, making it easier to manage and animate. In contrast, representing multiple bones with a single entry can lead to confusion in the deformation process and can complicate the animation workflow. Therefore, each bone should distinctly represent its respective bone in the rigged model for optimal results.
