Soft-Body Dynamics

Soft-body dynamics are handled in Maya by creating a set of particles that surround the object and influence it. When these particles collide with something or are moved by fields, the connected geometry moves with them. This is ideal for creating effects that mimic cloth and organic flexible materials. Soft-body dynamics are also used to create rigid yet flexible effects, such as objects that bounce and bend as though they were made of rubber or gelatin.

Using the default settings, soft bodies can infinitely inflate or deflate from almost any influence. To get a realistic response, you must add goals or springs. Goals give the object a target shape to move toward, like a rubber squeeze toy that un-squeezes back to its original shape. Alternatively, springs add a lattice of tensioned springs throughout the geometry, like adding a boxspring of rigidity to the object. In this section, you'll explore the springs approach to soft bodies.
