The general structure is done. However, you may also want to cut
an extra border outside the crack border loop, as shown in the cen-
ter in Figure 3-70, to improve the local tension.
Thickness
Primitives and polygons by default don’t have any thickness. If you
delete half of a polygon sphere, you’ll notice absolutely no thick-
ness. 3ds Max 6 has a tool named Shell Modifier that allows you to
give thickness to your object. In this section we show how to add
thickness to your mesh without using any special tool or script.
First, pick a sphere and delete half. Duplicate the object and
scale it down a bit.
