Material Groups

From ZBrush Info

Material Group will group the model based on shaders assigned in other 3D applications. The model will have to be exported from the other application with Material information in the OBJ file format.

To turn this on you must enable Preferences: Importexport: Import Mat before importing the mesh. Material Groups is very useful for transfering grouping information from other applications into ZBrush.
