RemoveFlexEnvDefo rmer

Introduced

1.0

Description

Removes deformers from an envelope. Every point in an envelope is assigned to one or more deformers. For each point, weights control the relative influence of its deformers.

Deformers are the objects that control the shape of the envelope. You pick the deformers when you first create an envelope deformation, but you can still add and remove deformers later if necessary.

Although it is common to use skeletons as deformers, you can actually use any object. The geometry of a deformer does not matter because the points of the envelope are assigned to its center. (Bones are the exception--points are deformed by the whole length of a bone.)

Whether you use a cube, a sphere, or a null, all transformations of the surrounding envelope are relative in size, orientation, and position to the deformer's center, not its shape. Nulls and implicit objects are good choices because they do not render.

Scripting Syntax

    RemoveFlexEnvDeformer( [ConnectionSet], [Interactive] )

Parameters

Parameter | Type | Description
ConnectionSet [in/out] | ConnectionSet | Specifies the envelope and the deformer objects to remove. 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

VBScript Example

    'This example builds an envelope made of 2 skeleton objects on a sphere
    'and a cylinder. Then, it removes individual deformers from the cylinder,
    'and all envelope components from the shere.
    '
    'The deformers removed from the cylinder are outputted in the log.
