On the enclosed DVD, you'll find a video walk-through of the creation and sculpting of the cloth object.
Sculpting with Falloffs
Falloffs can be used with sculpting the same way that they are with other modeling functions. For ex-
ample, if you want to sculpt some detail near the top of the cloth without affecting the flat surface, you
can implement a small Linear falloff in which the top surface has zero effect, and the effect increases as
it moves downward. This can also be an effective method for smoothly increasing the volume of folds
in fabric. Set the falloff to begin where the fold should originate and end where the fold reaches full
strength. That way, with one clean stroke, you can create a complex fold.
Modeling Semi-Organic Objects
The first modeling subject to consider is one that features a combination of smooth, organic curves and sharp
edges. Many objects in the real world are not simply organic or hard surfaced, but contain attributes of both
types of models. The first subject for this scene will be a stylized bottle that contains such elements. The
bottle will have a mix of complex curves and edges that gradually sharpen. Although this subject is too rigid
for sculpting tools to create, it would be very difficult to build without utilizing falloffs, action centers, and
weight map-derived surface creases. The end goal is a bottle like the one shown in
Figure 5-23
