ZBrush 2 employs powerful code and feature innovations to boost the artist's productivity. Some of the highlights of these innovations include: Multi-Resolution Mesh Editing: Models can be edited in multiple mesh-resolution levels, enabling artists to add low- or high-frequency details on the appropriate level, while ZBrush transfers the changes to other levels. Displacement and Normal Maps: Building upon the Multi-Resolution Mesh Editing functionality, detailed maps can be generated for low-resolution base meshes.

Visibility Controls: Portions of any mesh can be hidden, offering numerous advantages. Artists can concentrate on areas of interest, and use selective hiding to add edge loops and other mesh-enhancement features.

New Sculpting Brushes: Nine new sculpting brushes provide new ways of adding detail to meshes of any resolution in intuitive ways.

Displacement Projections: Using depth-enabled paintbrushes and tools, mesh displacements can be applied by simply brushing them onto the surface of an object.
