Flags

Long name (short name)	Argument types	Properties
-after(-af)
If the default behavior for insertion/appending into/onto the existing chain is not the desired behavior then this flag can be used to force the command to place 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. Works in create mode (and edit mode if the deformer has no geometry added yet).
-afterReference(-ar)
The -afterReference flag is used to specify deformer ordering in a hybrid way that choses between -before and -after automatically. If the geometry being deformed is referenced then the -after mode is used when adding the new deformer, otherwise the -before mode is used. The net effect when using -afterReference to build deformer chains is that internal shape nodes in the deformer chain will only appear at reference file boundaries, leading to lightweight deformer networks that may be more amicable to reference swapping.
-before(-bf)
If the default behavior for insertion/appending into/onto the existing chain is not the desired behavior then this flag can be used to force the command to place 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. Works in create mode (and edit mode if the deformer has no geometry added yet).
-deformerTools(-dt)
Returns the name of the deformer tool objects (if any) as string string ...
-envelope(-en)	float
Envelope of the delta mush node. The envelope determines the percent of deformation. Value is clamped between to [0, 1] range. Defaults to 1.
-exclusive(-ex)	string
Puts the deformation set in a deform partition.
-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. Works in create mode (and edit mode if the deformer has no geometry added yet).
-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 ...
-geometryIndices(-gi)
Complements the -geometry flag in query mode. Returns the multi index of each geometry.
-ignoreSelected(-is)
Tells the command to not deform objects on the current selection list
-includeHiddenSelections(-ihs)
Apply the deformer to any visible and hidden objects in the selection list. Default is false.
-name(-n)	string
Used to specify the name of the node being created.
-parallel(-par)
Inserts the new deformer in a parallel chain to any existing deformers in the history of the object. A blendShape is inserted to blend the parallel results together. Works in create mode (and edit mode if the deformer has no geometry added yet).
-pinBorderVertices(-pbv)	boolean
If enabled, vertices on mesh borders will be pinned to their current position during smoothing. Defaults to true.
-prune(-pr)
Removes any points not being deformed by the deformer in its current configuration from the deformer set.
-remove(-rm)
Specifies that objects listed after the -g flag should be removed from this deformer.
-smoothingIterations(-si)	uint
Number of smoothing iterations performed by the delta mush node. Defaults to 10.
-smoothingStep(-ss)	float
Step amount used per smoothing iteration. Value is clamped between [0, 1] range. A higher value may lead to instabilities but converges faster compared to a lower value. Defaults to 0.5.
-split(-sp)
Branches off a new chain in the dependency graph instead of inserting/appending the deformer into/onto an existing chain. Works in create mode (and edit mode if the deformer has no geometry added yet).

Flag can appear in Create mode of command	Flag can appear in Edit mode of command
Flag can appear in Query mode of command	Flag can be used more than once in a command.
