= 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.
