Depending on the complexity of your objects and the desired effect, you can
use either method. The following sections go into more detail about them.

soft body.
FFD-based soft bodies on page 4043: Soft bodies deformed by an FFD modifier

The Soft Body modifier lets you turn a rigid body into a closed, deformable,
3D triangular mesh, thus creating objects that can be flexed, bent, and
squashed during the simulation. You can specify physical properties for soft
bodies, including stiffness, mass, and friction.
reactor provides two types of soft body: mesh-based soft bodies, where reactor
deforms the underlying mesh directly; and Freeform Deformation (FFD) bodies,
in which reactor encases the original mesh in a simpler lattice that it uses to
update the mesh. For more information about creating FFD bodies, see
FFD
Soft Bodies
on page 4043.
To add a soft body to the simulation, you need to add it to a
Soft Body
Collection
on page 4046.
Procedures
To create a soft body:
1 Create the mesh to use as the basic, non-deformed state of your soft body.
You can turn any mesh with a fixed number of vertices into a soft body.
2 With the object selected, choose one of the above commands.
The reactor SoftBody modifier appears in the object's modifier stack.
