pymel.core.animation.blendShape

blendShape(*args, **kwargs)

This command creates a blendShape deformer, which blends in specified amounts of each target shape to the initial base shape. Each base shape is deformed by its own set of target shapes. Every target shape has an index that associates it with one of the shape weight values.In the create mode the first item on the selection list is treated as the base and the remaining inputs as targets. If the first item on the list has multiple shapes grouped beneath it, the targets must have an identical shape hierarchy. Additional base shapes can be added in edit mode using the deformers -g flag.

Flags:

• after : af (bool) [create,edit]

  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. Works in create mode (and edit mode if the deformer has no geometry added yet).

• before : bf (bool) [create,edit]

  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. Works in create mode (and edit mode if the deformer has no geometry added yet).

• deformerTools : dt (bool) [query]

  Returns the name of the deformer tool objects (if any) as string string ...

• envelope : en (float) [create,query,edit]

  Set the envelope value for the deformer, controlling how much of the total deformation gets applied. Default is 1.0.

• exclusive : ex (unicode) [create,query]

  Puts the deformation set in a deform partition.

• frontOfChain : foc (bool) [create,edit]

  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 (unicode) [query,edit]

  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 ...

• ignoreSelected : ignoreSelected (bool) [create]

  Tells the command to not deform objects on the current selection list

• inBetween : ib (bool) [create,edit]

  Indicate that the specified target should serve as an inbetween. An inbetween target is one that serves as an intermediate target between the base shape and another target.

• name : n (unicode) [create]

  Used to specify the name of the node being created

• origin : o (unicode) [create]

  blendShape will be performed with respect to the world by default. Valid values are worldand local. The local flag will cause the blend shape to be performed with respect to the shape’s local origin. Flag can have multiple arguments, passed either as a tuple or a list.

• parallel : par (bool) [create,edit]

  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).

• prune : pr (bool) [edit]

  Removes any points not being deformed by the deformer in its current configuration from the deformer set.

• remove : rm (bool) [edit]

  Specifies that objects listed after the -g flag should be removed from this deformer.

• split : sp (bool) [create,edit]

  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).

• target : t (unicode, int, unicode, float) [create,query,edit]

  Set target object as the index target shape for the base shape base object. The full influence of target shape takes effect when its shape weight is targetValue. Parameter list: string: the base objectint: indexstring: the target objectdouble: target value

• topologyCheck : tc (bool) [create]

  Set the state of checking for a topology match between the shapes being blended. Default is on.

• weight : w (int, float) [create,query,edit]

  Set the weight value (second parameter) at index (first parameter).

• weightCount : wc (int) [create,query,edit]

  Set the number of shape weight values.
