This timelapse video shows the creation of a model while demonstrating a number of the new tools in Pixologic ZBrush 2.0. It starts by showing the new ZSphere tools available. Then the video focuses strictly on sculpting the resulting mesh using tools like the new Projection Master, the Smooth Brush, and the Pinch Brush. it finishes by showing the process of making a displacement map, and applying it back to the model. The end result is a model that is over 2.8 million polygons!
