and how those two shapes will relate. At this stage I am almost entirely using the Move brush to create
these shapes. (See Figure 2-24 . )
2. Using the Standard brush I sketch in cheekbones ( Figure 2-25 ) . This is a very quick, rough stroke. The
only point is to start to define the edges of the face and its shape. Don't spend too much time working on
skeletal anatomy yet. We are too early in the process to think about secondary anatomical forms in detail.
Right now, we want big shapes and their relationships to each other.
3. Add a sphere for the eye by appending a Polysphere into the SubTool stack. Use the Transpose Move
tool to place the eye where you want it. I chose to place them wide and just below the midpoint of the
head. Place the spheres for the eyes early so that you can be sure as you sculpt the anatomy of the eye,
both the bony and fatty forms, that they will be relating back to the eye's spherical shape. Otherwise you
will make it far harder on yourself to be accurate because you have no point of reference. Changing their
position later is extremely easy with Transpose and the Move brush.
When the eye is roughly placed, use the ZScript SubTool Master to mirror it across the X axis. Press the
Mirror button and choose the options Across X axis and Merge into one SubTool. SubTool master must
be installed and is available for free from www.pixologic.com . Here we see the eye after mirroring with
the ZScript SubTool Master ( Figure 2-26 ) .
Using the Standard brush in conjunction with Clay Tubes and Polish, refine the shape of the eyelids and
cheekbones ( Figure 2-27 ). Be sure to use Transparency mode as you work, With Transparency and Ghost
buttons turned on, you will be able to see both the eyelid and the shape of the sphere beneath it. This is
invaluable to help conform the eyelids around the sphere of the eyeball. If you cannot see through the
SubTools as shown in the image below, be sure to turn on Ghost mode. The button is located on the right
of the screen just below the Transp button.
