62 chapter 2 ■ Sculpting in ZBrush
- Using the Clay brush, add the two-pronged shape here. Notice how it connects to the
corners of the mouth. When we add skin, the combined effect of the zygomatic major
and minor, buccinator, and triangularis creates an important form on the skin since
they all pull that one area (Figure 2.55). - Mask out the recesses of the eye sockets. Stepping down subdivision levels (so the
effect of the brush is stronger) smooths the faces to pull them closer to the surface
(Figure 2.56).
Figure 2.54 Sculpting the frontalis
Figure 2.55 The levator labii muscles appear as two triangles coming down either side of the
nose. Zygomaticus muscles connect the cheekbones to the corners of the mouth.
Adding the Eyes
We’ll now create a sphere for the eyeball and add it as a subtool to the current model. The
typical human eyeball is about 28 mm. It’s best to make sure the sphere fills out the socket
with a slight give on each corner. The depth of the eye can be determined by the angle in
Figure 2.57. A diagonal drawn between the brow bone and the cheekbone should just touch
the corneal bulge of the eyeball. Remember that you can fill the eye subtool with a material
so it will display the same value as the other tools.
