Keyframe rollout
Use Current Stored K eys—When on, the animation
used for these vertices is that after the reactor
modifier is applied. In other words, if the modifier
contains any key frames, reactor uses those for
the animation. When off, reactor evaluates t he
animation before the reactor modifier is applied,
thus ignoring any stored key frames.

Pr ocedur es
To f ix vertices i n a deformable body to a r igid body:
1.
On the Modify panel, click Vertex in the
deformable body modifier’s sub-object list.
This lets you select individual vertices in the
deformable body.
2. On the C onstra ints rollout, click Attach To
Rigid Body.
The new constraint appears in the Constraints
list.
3. Ensure the constraint is selec ted in the
Constraints list; this makes the Attach To
RigidBody rollout available.
4. On the Attach To RigidBody rollout, click the
Rigid Body pick button and then select the
body to w hich to constrain the ver tices.
5. Select the vertices to constrain in the
deformable body.
During the simulation, these vertices maintain
their positions relative to the rigid body.
6. When finished, it’s advisable to exit the Vertex
sub-object level, to keep f rom accidentally
deselecting some of the constrained vertices
before simulat ing.
