In this video I will walk through a new feature found in ZBrush3.5R3. There is a new sub-palette found in the Tool Palette at Tool>Visibility.
With this new feature it is extremely easy to split up a tool into multiple subtools. In the video I will demo how to take a mesh that has several mesh shells with one polygroup and convert that mesh into multiple subtools.
In the video you will also see how easy it is to select parts of a mesh now with a few keys strokes.
