Create the Lower Body
The lower body spinal section and pipes are created using a combination of tools. The pipes are generated
with ZSketch, using the same technique as before. The lumbar (lower) spinal section is created using
ZSketch and the Group Loops function to create the more intricate details. Follow these steps to create the
lower body section. Be sure to check the DVD or download files for a video that details how to use ZSketch
in conjunction with Group Loops to create unique forms like this.
1. Append a ZSphere into the SubTool stack. Draw a chain that extends from the torso down toward the
hip area. Make sure it is long enough to feel like a functional waist and spine for the character. You will
want to use this form to balance the upper body. Draw a few branches off the central ZSphere chain as
seen in Figure 6-51 . This structure is designed to mirror the configuration of the lumbar vertebrae, only
larger and mechanical in nature ( Figure 6-52 ) .
