232 chapter 7 ■ Transpose, ZSphere Rigging, Retopology, and Mesh Extraction
We will manually delete the subtools in this exercise to help illustrate a new delete option
in ZBrush 4. An alternate approach to this step is to simply select the body subtool and
click the Clone button. This will create a new copy of just the body subtool.
When you delete subtools, ZBrush will open a dialog box letting you know this is not
an undoable action. ZBrush will offer you three options in this box:
• Cancel will stop the operation entirely.
• OK will delete the current tool.
• Always OK will delete the current tool and prevent ZBrush from warning you again
for the remainder of this session. When you choose this option, you will be able to
delete subtools with no pop-up window.
This setting will automatically reset the next time you start ZBrush. This is to help pre-
vent you from deleting subtools unintentionally since this action cannot be undone.- Step down several subdivision levels. Transpose posing is more difficult when the mesh
is dense. It is not necessary to have thousands of polygons when you are simply posing
the model. - Ctrl-drag a mask from the arm to the chest. This is masking by topology. You may also
enter Draw mode (the Q key) and paint the mask directly as you would normally. Once
the arm is masked, invert the mask so that the body is masked and the arm unmasked
by Ctrl-clicking the background. - With the arm unmasked, draw a transpose line from the shoulder to the wrist. Move
to a side view and place the endpoint where the arm should pivot (Figure 7.11).

- Repeat this process for the legs, but this time turn on X Symmetry with the X hotkey.
Notice how two action lines are created, and you can move the legs together (Figure 7.12).
