You can create subcharacter sets within previously defined character sets. When you create a subcharacter set, Maya adds the subcharacter set to the current character set. This is useful because you can apply the power of Maya’s character animation features to parts of a character’s hierarchy.
Creating subcharacter sets is similar to creating character sets: you select a character’s objects that you want to define as a subcharacter set (for example, the objects that make up the character’s face) and then select Character > Create Subcharacter Set. The creation options for subcharacters are the same as the options for creating characters.
