==== Summary ====

In Unity, the bone structure for Humanoids (characters) are standardized for the efficiency of productions.\\
The Humanoid bone structure designated by Unity is called **UnityHumanoidAvatar**.

Unity doesn't control the bones directly, instead, it remaps the bones of a 3D character to UnityHumanoidAvatar and the result of the HumanoidAvatar being controlled is applied to the character's bones to animate the character.
