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 pro perties for soft bodies, including
stiffness, mass, and f riction.
reactor provides two types of soft body:
mesh-based soft bodies, where reactor deforms
the underlying m esh 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
(page 2–786).
To add a soft body to the simulation, you need to
add it to a Soft Body Collection (page 2–788).
Pr ocedur es
To create a soft body:
1.
Create the mesh to use as the basic,
non-deformed state of your soft body. You can
turnanymeshwithafixednumberofvertices
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.
To edit a sof t body’s physical pr oper ties:
1.
Select an appropriate object in the scene.
2. On the Modify panel, ensure that the reactor
SoftBody modifier is highlighted in the
modifier stack.
3. Use the Properties rollout to edit the properties,
which are described in the Interface section,
following.
