Disconnects a shader from the specified shader connection points.

Scripting Syntax

oReturn = RemoveShaderFromCnxPoint( [Source], [InputObjs], [DeleteOnLastDisconnection] );

Return Value

Returns the disconnected shader.


Parameter Type Description
Source String Shader to disconnect.

Default Value: Current selection

InputObjs String List of connection points.

Default Value: Current selection

DeleteOnLastDisconnection Boolean True to delete existing shaders that are disconnected by this command.

Default Value: True


VBScript Example

' This example creates a sphere, applies a lambert shader to it, prints out
' the list of connection points to that shader, disconnects the shadow and
' photon connection points from the shader and then prints the updated list.
' Create the sphere to which the shader will be connected
set oSphere = CreatePrim( "Sphere", "NurbsSurface" )
' Apply a lambert shader to instantiate the material
set oShader = SIApplyShader( InstallationPath( siFactoryPath ) _
                                & "\Data\DSPresets\Shaders\Material\Lambert.Preset", _
                                oSphere, "Christopher" )
' Convert the shader to a Shader object 
set oShader = oShader(0)
' Print shader info (before disconnecting)
printShaderInfo oShader
' For convenience, create a collection to hold the parameters
' to be disconnected (Shadow and Photon connection points).
set oCnxPoints = CreateObject( "XSI.Collection" )
oCnxPoints.Add oSphere & ".material.Shadow"
oCnxPoints.Add oSphere & ".material.Photon"
' Use that collection to disconnect the shader from the material 
RemoveShaderFromCnxPoint oShader, oCnxPoints
' Print shader info (after disconnecting)
printShaderInfo oShader
' This is a convenience routine that prints information about the shader
sub printShaderInfo( in_shader )
        ' From the shader object you can get the material it belongs to
        set oMaterial = in_shader.Owners(0)
        ' Use the material to return the parameters that are connected and
        ' print out their names
        for each p in oMaterial.Parameters
                if TypeName( p.Source ) <> "Nothing" then
                        LogMessage p.ScriptName & " is connected to " & p.Source.Name
                end if
end sub
' Output of the above script:
' ...before disconnecting
'INFO : "surface is connected to Christopher"
'INFO : "shadow is connected to Christopher"
'INFO : "Photon is connected to Christopher"
' ...after disconnecting
'INFO : "surface is connected to Christopher"
