SUMMARY
=======
 
If you set Clusters (with a Cluster Center) on an Envelope's surface, when
the Envelope is deformed as a result of translating an IK chain End
effector, the Cluster centers do not follow the Global position of the
envelope. The Cluster centers are usually offset, therefore affecting the
transformations of the Clusters.
 
To correct this behavior, substitute the Cluster centers with objects
converted to skeletons (Skeleton>Group as skeleton). Then, weight the
points that were set for the Clusters to the new "Group-as-skeleton"
object.
 
The new "Group-as-skeleton" object will follow the transformations of the
Envelope without any position offsets.
