■ Sculpting the Skull 51• The third line represents the bottom of the nose.
• The last third of the head is divided into thirds
itself. This is represented by the two smaller
lines on the image. The first line marks the line
between the lips, and the second denotes the
midpoint between the lip and chin.Saving Your Work
As you work through this chapter, you will want to
save your work often. You always want to save your
work as ZTools rather than as models or documents
because ZTools carry all your model, texture, and
sculpting information. You can save projects under
the File menu at the top of the screen. Now let’s get
started sculpting!
There is one more option for saving your work. ZBrush now supports the ZBrush Project
format. This is a single file that saves your document settings, light, material, texture, poly-
paint, model, timeline, and sculpting information. Any and all info regarding your work is
saved in this file.Sculpting the Skull
To begin, you will sculpt a generalized human skull
from a ZBrush primitive sphere. This exercise describes
a high-resolution sculpting method. The sculpting pro-
cess begins at a higher subdivision level, and the form
will be built using the Claytubes and Rake brushes.
As discussed in Chapter 1, complex shapes can
be broken down into simpler forms for easier study
and replication. The initial shape you want to strive
for is shown in Figure 2.26. Notice the rounded facial
plane and the overall simplification of the head into a
single basic shape. By working toward this first step
and building all the secondary forms on it, you can
maintain a sense of structural integrity throughout
the sculpting process.
During this exercise several bony landmarks will
be of interest. These are points that we want to find in
the sculpture and ensure are in correct spatial relation-
ship to one another. Failure to find these points or keep

form similar to those shown here.Figure 2.25 The human skull with measuring guides
