Go to: Related nodes. Attributes.

The cluster node deforms one or more geometries by transforming them by some percentage of the transformation of another object in the scene. The default percentage is one, so the default cluster will rigidly deform the geometries.

A different percentage can be associated with each CV in the deformed object.

The accuracy of the deformation is controlled by the percentResolution attribute.

The envelope attribute can be used to globally attenuate the amount of deformation.

Long name (short name)TypeDefaultFlags
percentResolution (ptr) float5outputinputstorable
resolution by which cluster percents can differ without being lumped together as a single percentage for efficiency
usePartialResolution (upr) enum0outputinputconnectablestorable
whether or not to use the partial resolution
relative (rel) boolfalseoutputinputconnectablestorable
relative => only use weighted node i.e. no pre, post matrix
clusterXforms (x) compoundn/aoutputinputconnectable
the bundled cluster transforms
preMatrix (pre) matrixidentityoutputinputconnectable
Represents the transformation in the DAG above the weighted node.
weightedMatrix (wt) matrixidentityoutputinputconnectable
cluster weighted matrix
postMatrix (post) matrixidentityoutputinputconnectable
Represents the transformation in the DAG below the weighted node.
weightedCompensationMatrix (wcm) matrixidentityoutputinputconnectablestorablehidden
cluster weighted matrix compensation
geomMatrix (gm) matrixidentityarrayoutputinputconnectablestorablehidden
Matrix to set account for the geom matrix at cluster creation time.
matrix (ma) matrixidentityoutputinputconnectablestorable
transform that we will rigidly deform by when all percentages are at one
bindPreMatrix (pm) matrixidentityoutputinputconnectablestorable
compensation matrix used when we rigidly deform the geometry
bindState (bs) boolfalseoutputinputconnectable
not used
postCompensationMatrix (psc) matrixidentityoutputinputconnectablehidden
WorldSpace matrix below cluster weighted matrix compensation
preCompensationMatrix (prc) matrixidentityoutputinputconnectablehidden
WorldSpace matrix above cluster weighted matrix comp (-bs)
angleInterpolation (ait) enum0outputinputconnectablestorable
The direction of angle interpolation. In most cases 0 (Closest) will work the best. However, if components appear to be rotating in the wrong direction, a value of 1 (Positive) or 2 (Negative) may be needed.
