zbrush4 features mask brushes restangular and circular masks
Masks began as way of protecting surfaces so that they would be unaffected by your subsequent sculpting, painting. Over the 10 year history of ZBrush they have evolved to accommodate a wide variety of needs. Masks continue to protect surfaces, giving greater control as you work. They can also be used to define parts of your model that you wish to extract into whole new object. They are at the heart of Shadow Box – ZBrush’s powerful silhouette-based mesh generation tool. There’s no limit to what you can accomplish with masks!
