SILocalAssignFlexEn v

Introduced

1.0

Description

Reassigns the points of local flexible envelopes.

Scripting Syntax

    SILocalAssignFlexEnv( [SubComp], [ConnectionSet], [Interactive], [NbDeformersPerPoint] )

Parameters

Parameter | Type | Description
SubComp | String | List of points to be reassigned. Default Value: Current selection
ConnectionSet [in/out] | ConnectionSet | Specifies the envelope and the bone. See Operator Presets for details on the connection set required for this operator. Default Value: Currently selected objects are used as the main group. Warning: An error occurs if the connection set is invalid. Please verify the connection set required for this operator to avoid breaking your scripts.
Interactive | Boolean | True to prompt user to pick objects. Default Value: False
NbDeformersPerPoint | Integer | The maximum number of deformers that will affect each point during assignment. Default Value: 2

Return Value

Returns a XSICollection of the envelope assigment operators.

Examples

VBScript Example

    'This example creates an envelope on "BodyMan" model, with less bones
    'than usual (2 nulls for the body, 1 bone per arm).
    '
    'The default envelope assignment doesn't give a correct separation
    'between the arms and the body, so we will use LocalAssignFlexEnv,
    'SISmoothEnvWght and SymEnvWeight in order to modify the weight assignment.
