The Bottom Line
Control the behavior of soft body objects.
Soft body meshes suffer from a disadvantage in that they lack
internal structure. Although bending parameters can counter this somewhat, there are some cases in which
the fully 3D structure of a matrix can come in handy for giving a soft-body simulation more of a sense of
volume.

Try to construct a cube of gelatin from a mesh cube by using a soft-body-modified lattice for
the deformation. Figure out how best to weight-paint the cube so that the lattice deformation is convin-
cing.
Work with force fields, collision objects, and modifiers.
You can obtain realistic cloth movement effects
by combining rigging, pinning, and hook modifiers with the free movement of the cloth simulation.

Using a cloth setup similar to the curtains shown in this chapter, create a curtain that can be
animated to open in a realistic way, as though it were hung with hooks on a curtain rod.
Work with cloth and clothing.
Thereareavarietyofapproachestotakewithcreatingclothing,rangingfrom
modeling the cloth forms directly, to using the cloth simulator as a median step in modeling, to animating
with the cloth simulation directly. All of these approaches have their appropriate uses.
