Synopsis

cluster [-after] [-before] [-bindState] [-deformerTool] [-envelope double] [-exclusive] [-frontOfChain] [-geometry string] [-ignoreSelected] [-name string] [-prune] [-relative] [-remove] [-resetGeometry] [-split] [-weightedNode DAGobject DAGobject] [objects]

cluster is undoable, queryable, and editable.

Flags

Long name (short name)	[argument types]	Properties
-name(-n)	string
Used to specify the name of the node being created
-geometry(-g)	string
The specified object will be added to the list of objects being deformed by this deformer object, unless the -rm flag is also specified. When queried, this flag returns string string string ... In query mode, this flag needs a value.
-remove(-rm)
Specifies that objects listed after the -g flag should be removed from this deformer.
-before(-bf)
If the default behavior for insertion/appending into/onto the existing chain is not what you want then you can use this flag to force the command to stick the deformer node before the selected node in the chain even if a new geometry shape has to be created in order to do so
-after(-af)
If the default behavior for insertion/appending into/onto the existing chain is not what you want then you can use this flag to force the command to stick the deformer node after the selected node in the chain even if a new geometry shape has to be created in order to do so
-split(-sp)
Branches off a new chain in the dependency graph instead of inserting/appending the deformer into/onto an existing chain.
-frontOfChain(-foc)
This command is used to specify that the new deformer node should be placed ahead (upstream) of existing deformer and skin nodes in the shape's history (but not ahead of existing tweak nodes). The input to the deformer will be the upstream shape rather than the visible downstream shape, so the behavior of this flag is the most intuitive if the downstream deformers are in their reset (hasNoEffect) position when the new deformer is added.
-ignoreSelected(-is)
Tells the command to not deform objects on the current selection list
-deformerTool(-dt)
Returns the name of the deformer tool objects (if any) as string string ... In query mode, this flag needs a value.
-prune(-pr)
Removes any points not being deformed by the deformer in its current configuration from the deformer set.
-exclusive(-ex)
Puts the deformation set in a deform partition. In query mode, this flag needs a value.
-weightedNode(-wn)	DAGobject DAGobject
Transform node in the DAG above the cluster to which all percents are applied. The second DAGobject specifies the descendent of the first DAGobject from where the transformation matrix is evaluated. Default is the cluster handle. In query mode, this flag needs a value.
-bindState(-bs)
Specifying this flag adds in a compensation to ensure the clustered objects preserve their spatial position when clustered. This is required to prevent the geometry from jumping at the time the cluster is created in situations when the cluster transforms at cluster time are not identity.
-envelope(-en)	double
Set the envelope value for the deformer. Default is 1.0 In query mode, this flag needs a value.
-relative(-rel)
Enable relative mode for the cluster. In relative mode, Only the transformations directly above the cluster are used by the cluster. Default is off.
-resetGeometry(-rg)
Reset the geometry matrices for the objects being deformed by the cluster. This flag is used to get rid of undesirable effects that happen if you scale an object that is deformed by a cluster.
