You don’t need to know about character node behavior in order to use character sets effectively. If you are new to character sets, you can skip this section. However, familiarity with character node behavior can provide you with more control over character manipulation and performance.
For each object in your scene, if there has been any change to its node or any of the nodes in its history (its input or output nodes), Maya will evaluate the nodes and update the display based on the node’s node behavior attributes. The node behavior attributes for character nodes can affect how characters are evaluated and displayed.
