Creates a new empty partition of the specified type (either object or light) and inspects it. This is the scripting equivalent of deselecting everything in the scene and then selecting Pass - Partition > New from the Render menu.

Note: After creating an empty partition, you can add items to it, but CreatePartition and SICreatePartition command already performs both tasks simultaneously.

A partition is a division of a pass and behaves like a group. Partitions are used to organize scene elements within a pass. There are only two types of partitions, object and light. A render pass creates a picture layer of a scene that can be composited with any other passes to create a complete image.

Note: This command uses output arguments. C# and some scripting languages (such as JScript, PerlScript and Python) don't support arguments passed by reference so you need to use the best workaround for your situation:

For scripting languages this command returns an ISIVTCollection which you can use to get the output arguments.

For C# you can use the XSIApplication.ExecuteCommand method to call this command. ExecuteCommand packs the output arguments into a C# System.Object containing an Array of the output arguments (see Calling Commands from C#).

SICreateEmptyPartition( [Target], [Name], [Type], [Value] );

Parameter	Type	Description
Target	String	Pass to add the partition to. Default Value: Selected pass, or current pass
Name	String	Name of the new partition. Default Value: "Partition"
Type	siPartitionType	Type of the partition to create. Default Value: siObjectPartition
Value	XSICollection containing a Group object	Returns the new partition.

VBScript Example

'

'	This example demonstrates how to create an empty partition

'	and then add an object to it. It also shows how you can 

'	access partition information from a particular pass.

'

' Create a new scene 

NewScene , false

' Create a cone to add to one of the partitions

Set oCone = GetPrim( "Cone", "MeshSurface" )

' Create a standard (default) pass 

CreatePass , "PassMeBy", oPass

' Print partition info for default pass

getPartInfo oPass

' Now add an empty light partition to the pass and add the light to it

SICreateEmptyPartition oPass, "Sweet_Sorrow", siLightPartition, oLightPart

AddToPartition oLightPart(0), "Light"

' Print new partition info 

getPartInfo oPass

function getPartInfo( in_pass )

	Application.LogMessage "Partitions for " & in_pass & ":"

	Application.LogMessage "--------------------------------"

	' Create an XSICollection with the partition info

	set oParts = CreateObject( "XSI.Collection" )

	oParts.SetAsText in_pass & ".Partitions.*" 

	For Each p In oParts

		Application.LogMessage p

	Next

end function

' Output of the above script:

'INFO : "Partitions for Passes.PassMeBy:"

'INFO : "--------------------------------"

'INFO : "Passes.PassMeBy.Background_Objects_Partition"

'INFO : "Passes.PassMeBy.Background_Lights_Partition"

'

'INFO : "Partitions for Passes.PassMeBy:"

'INFO : "--------------------------------"

'INFO : "Passes.PassMeBy.Background_Objects_Partition"

'INFO : "Passes.PassMeBy.Background_Lights_Partition"

'INFO : "Passes.PassMeBy.Sweet_Sorrow"
