Since the shape of this level-1 mesh has changed, we can recall the original which was stored as a \C020202Morph Target\C484848 in Step 2.

Alternately, we could press the Tool>Import button again. Since multiple mesh-resolution levels are defined for the selected tool, ZBrush would assume we intend to import a mesh into the current level rather than creating a new tool.

If the original shape were unimportant, we could press the 'Cage' button, and ZBrush would generate a base shape optimal for receiving the displacement map.
