6. When you are done defining your shape, click the ShadowBox button again to exit.
   The mesh will now be available as a subtool for further sculpting (Figure 10.59). Note
   that the mesh will be automatically polygrouped in a logical manner.

Figure 10.59 The ShadowBox mesh ready for sculpting. Notice that the model is auto-

matically polygrouped when you exit ShadowBox.

You will now use group loops to isolate the poly-

groups with an edge loop cut by ZBrush. This allows

you to mask and move the grouped areas while main-

taining razor sharp angles in the mesh. Figure 10.60

shows a masked area of the mesh moved. Notice how

the edges are tagged compared to the looped area.

1. Select the Mask Pen brush and, while holding
   down Ctrl, mask out a section of the side of the
   object (Figure 10.61). Click Tool → Polygroups →
   From Masking to create polygroups based on the
   masked area (Figure 10.62).


2. The edges of this group will be jagged due to
   the lower poly count of the object. To cut new
   edge loops around the polygroups, click Tool →
   Geometry → GroupsLoops (Figure 10.63).
   Figure 10.64 shows the resulting loops.

Figure 10.60 The circles on top were moved by using a
mask only to isolate the faces. The bottom used group
loops. Notice the far better quality of the edges on the
bottom model.
