## RemoveAllShadersFromCnxPoint

### Introduced

v1.0

### Description

Disconnects all shaders from the specified shader's connection points, without the need to know information about the connected shaders or if shaders are indeed connected.
The second argument allows the user to specify in detail what types of shader connections should be disconnected.
Note: Shaders that are not used anymore once disconnected are automatically deleted.

### Scripting Syntax

    RemoveAllShadersFromCnxPoint( [InputObjs], [Type] );

### Parameters

Parameter | Type | Description
--- | --- | ---
InputObjs | String | List of connection points. Default Value: Current selection
Type | siShaderCnxPointType | Types of connection points to disconnect. Default Value: siShaderCnxPointAll

### Examples

#### VBScript Example

    '
    ' This example demonstrates how to disconnect shaders on a scene object. It
    ' also shows how you can find out whether the object's material is connected
    ' to a shader or a texture.
