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.

| 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
... |
|
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. |
