The following illustration shows the effect of using this option. The cloth tube
on the left has a keyframed top and a simulated bottom, with a visible join.
The cloth on the right uses soft selection to blur the line between the two.
Procedures
To use soft selection when animating a deformable body:
1 Before you apply the reactor modifier to a deformable body, apply a
modifier that has a Soft Selection option to your object, such as
Edit Mesh
on page 1353 or Mesh Select on page 1527.
You can also apply this modifier to the body later, but it's important that
it be below the reactor modifier in the object's modifier stack.
2 Follow the instructions in
Keyframing Vertices on page 4065 to keyframe
selected points for the deformable body, then create your reactor
animation.
3 With the body selected, open the selection modifier in the modifier stack,
and access the Vertex sub-object level.
4 Select the vertices that should appear fully physically simulated. For
instance, for a piece of cloth where the top section is keyframed, you
