blendShape

Go to: Related nodes. Attributes.

This node takes geometry as input and deforms it based on pairs of target shapes and weight values, to produce a new shape that is the specified blending of the input shapes.

Long name (short name)	Type	Default	Flags
topologyCheck (tc)	bool	true
Should the deformation check to see if the input topologies match?
weight (w)	float	0
The array of weight values (one per target shape)
icon (icn)	string	NULL
The name of a file containing an icon per target shape (not currently supported).
inputTarget (it)	compound	n/a
Bundled list of target info for a shape that is being deformed. The array index of this attribute corresponds to the array index of the input attribute, meaning that this target info is used to deform a given input shape.
inputTargetGroup (itg) compound n/a Bundled group of target information for a particular target weight. The array index of this attribute corresponds to the array index of the weight attribute, meaning that the corresponding weight value controls this target. inputTargetItem (iti) compound n/a Collection of all targets in a sequential target chain. The array index of this attribute is used to control which two target items we are interpolating between with the relationship: index = wt * 1000 + 5000. Thus a weight of 1 corresponds to the index 6000. An inbetween placed at a weight of 0.5 would be at the index 5500. inputGeomTarget (igt) geometry NULL The target geometry input inputPointsTarget (ipt) pointArray NULL Delta values for points in a target geometry. inputComponentsTarget (ict) componentList NULL Component list for points in a target geometry. targetWeights (tw) float 1.0 The weights themselves, in the same order as the components deformed by the deformation. normalizationId (nid) integer 0 The ID of the normalization group that includes this target, or zero for no normalization.
baseWeights (bw) float 1.0 The weights associated with the base shape, in the same order as the components deformed by the deformation.
normalizationGroup (ng) compound n/a Bundled group of normalization information for a particular normalization group ID. normalizationUseWeights (nuw) bool false Controls whether this normalization group uses the normalizationWeights in the normalization calculation. normalizationWeights (nw) float 1.0 The normalization weights, in the same order as the components deformed by the deformation.
paintTargetWeights (pwt) float 1.0 Temporarily stores the weights for one of the targets during painting.
paintTargetIndex (pti) integer 0 Tracks which target is being painted. The value corresponds to the index of the inputTargetGroup or normalizationGroup attribute. If value < 0, normalization group (-value) is indicated.
origin (or)	enum	1
Specifies the space in which point deltas are calculated. Valid values are 0 = "world", 1 = "local", 2 = "user".
baseOrigin (bo)	double3
When the origin flag is userDefined, the origin of the base shape is computed with respect to this point.
baseOriginX (bx) distance (double) 0.0cm X position of baseOrigin.
baseOriginY (by) distance (double) 0.0cm Y position of baseOrigin.
baseOriginZ (bz) distance (double) 0.0cm Z position of baseOrigin.
targetOrigin (to)	double3
When the origin flag is userDefined, the origin of the target is computed with respect to this point.
targetOriginX (tx) distance (double) 0.0cm X position of targetOrigin.
targetOriginY (ty) distance (double) 0.0cm Y position of targetOrigin.
targetOriginZ (tz) distance (double) 0.0cm Z position of targetOrigin.
parallelBlender (pb)	bool	0
This is true if the blendShape is used to blend parallel deformations.
useTargetCompWeights (itcw)	bool	true
This attribute is used internally to enable/disable the use of the per target component weights during evaluation
supportNegativeWeights (sn)	bool	0
Set to true if weights below -5 will be used in a target group. When this is off, blending between in-between shapes only supports weights >= -5.0. Enabling this attribute allows interpolation to in-betweens at numbers less than -5.0.
paintWeights (ptw)	doubleArray	empty
Legacy attribute left in to provide file format compatibility with Maya 2012 Gold/Hotfix 1.
