66 chapter 2 ■ Sculpting in ZBrush
Sculpting Skin and Fat on the Face
In this section we’ll finish sculpting the face by adding the skin and fatty tissue over the
bone and muscle sculpted so far. Having the structural elements of the skull and muscles in
place makes this is a much simpler process.
Begin by filling the head with the White Cavity material using Color → Fill Object
while only M is active and the White Cavity material is selected. Then follow these steps:- Using the Claytubes brush with a low ZIntensity setting, begin to refine between the
rake marks of the cheeks. The Clay brushes have the nice effect of adding material to
the low points first, making this an ideal way to fill out rake marks on a sculpt. You
will need to adjust the Claytubes brush for an ideal effect. First turn off the brush
Alpha. Then choose Brush → Depth and set the Imbed value to 0. This ensures that
the brush will add to the lower levels first (Figure 2.68).
There are fat deposits at the cheeks; sometimes they can be thinner in well-built
individuals, showing the line of the masseter muscle as a delineated plane change.
Continue up the face, taking care not to disturb the form as much as fill out the recessed
areas (Figure 2.69).
Figure 2.69 Filling out skin with the Claytubes brush- Using a smaller rake size with ZAdd on, move across the transitions between forms,
trying to tie them together. Take care to rake in the direction of the flow of the form
(Figure 2.70). - To reduce the roughness of the surface and take down the rake marks while maintain-
ing the form you have created, select the Smooth brush and set the BrushMod slider to
–100. Then lower your ZIntensity and smooth out the rakes (Figure 2.71). - Mask out the area next to the nose (this is called the nasolabial fold). While most
prominent in the old or obese, it is present in all faces and we want to accentuate the
plane change here (Figure 2.72). Invert the mask; you can now build up the fold of skin
while maintaining the areas around it. This method of sculpting against masks is a use-
ful way to create folds and wrinkles.
