Keyframe rollout
Use Current Stored Keys When on, the animation used for these vertices is
that after the reactor modifier is applied. In other words, if the modifier
contains any keyframes, reactor uses those for the animation. When off, reactor
evaluates the animation before the reactor modifier is applied, thus ignoring
any stored keyframes.
Attaching Vertices to a Rigid Body
reactor modifier (Cloth/Soft Body/Rope) > Constraints rollout
The Attach To Rigid Body constraint allows you to fix vertices in a deformable
body to a particular rigid body.
