ZBrush Face Tools is a new plugin that integrates Character Creator 4's character creation tool with ZBrush, Maxon's digital sculpting software.  The plugin simplifies the process of refining a head mesh in the Character Editor in ZBrush by allowing you to generate a basic head, bring it into ZBrush for sculpting and detail painting, including custom facial wrinkles, and then transfer the changes back to the Character Creator.
