blendShape is undoable, queryable, and editable.
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.

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 ...
|
|
geometryIndices(gi)
|
boolean
|
|
|
Complements the -geometry flag in query mode. Returns
the multi index of each geometry.
|
|
remove(rm)
|
boolean
|
|
|
Specifies that objects listed after the -g flag should
be removed from this deformer.
|
|
before(bf)
|
boolean
|
|
|
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).
|
|
after(af)
|
boolean
|
|
|
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).
|
|
afterReference(ar)
|
boolean
|
|
|
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 -after mode is used in adding the new deformer
otherwise -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.
|
|
split(sp)
|
boolean
|
|
|
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).
|
|
frontOfChain(foc)
|
boolean
|
|
|
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).
|
|
parallel(par)
|
boolean
|
|
|
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).
|
|
ignoreSelected(ignoreSelected)
|
boolean
|
|
|
Tells the command to not deform objects on the
current selection list
|
|
deformerTools(dt)
|
boolean
|
|
|
Returns the name of the deformer tool objects (if any)
as string string ...
|
|
prune(pr)
|
boolean
|
|
|
Removes any points not being deformed by the deformer in
its current configuration from the deformer set.
|
|
exclusive(ex)
|
string
|
|
|
Puts the deformation set in a deform partition.
|
|
envelope(en)
|
float
|
|
|
Set the envelope value for the deformer, controlling
how much of the total deformation gets applied. Default is 1.0.
|
|
target(t)
|
[string, uint, string, float]
|
|
|
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 object
- int: index
- string: the target object
- double: target value
|
|
inBetween(ib)
|
boolean
|
|
|
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.
|
|
topologyCheck(tc)
|
boolean
|
|
|
Set the state of checking for a topology match between the
shapes being blended. Default is on.
|
|
weight(w)
|
[uint, float]
|
|
|
Set the weight value (second parameter) at index (first parameter).
|
|
weightCount(wc)
|
uint
|
|
|
Set the number of shape weight values.
|
|
origin(o)
|
string
|
|
|
blendShape will be performed with respect to the
world by default. Valid values are "world" and "local". The local flag will cause the blend
shape to be performed with respect to the shape's local
origin.
|
|
normalizationGroups(ng)
|
boolean
|
|
|
Returns a list of the used normalization group IDs.
|
|
|
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 have multiple arguments, passed either as a tuple or a list.
