Quadrupeds have different proportions than human bipeds. In particular:
■ The rib cage is elongated downwards, unlike the flatter human rib cage.
■ The shoulder blades lie along the side of the rib cage, not on the back.
■ There are no collarbones.
The lack of collarbones gives the shoulder blades more freedom. This affects
weight distribution on the front legs.
When you use Biped to animate a quadruped, its “clavicle” parts behave
more like shoulder blades.
In spite of these differences, and some others we will mention later, a 3ds Max
Biped can model a quadruped quite well.
Set Up the Scene
The first steps are to configure animation for the walk cycle, and then to adjust
the biped
