MObject create	(	bool	UIvisible = `true`,
		MStatus *	ReturnStatus = `NULL`
	)

Creates a new volume light dependency graph node and adds it to the dependency graph.

If the UIvisible parameter is true, the new node will be connected to the light classification node (which allows the UI to recognize the node as a light) and added to the default light list. If UIvisible is false, the node will be created in isolation.

The light node is added to the current model, under a new transformation.

Parameters

[in]	UIvisible	determines whether or not to connect the new node to the light classification node and add it to the default light list.
[out]	ReturnStatus	return status

Returns: MObject representing the new dependency node.

Status Codes:

MS::kSuccess operation successful
MS::kInsufficientMemory ran out of memory
MS::kNoModelActive no model is currently active
MS::kLicenseFailure application not licensed for attempted operation
MS::kFailure the new node could not be added to the model, or the function set could not be properly initialized with the new object.

Examples:: volumeLightCmd/volumeLightCmd.cpp.

MObject create	(	const MObject &	parent,
		bool	UIvisible = `true`,
		bool	wantTransform = `false`,
		MStatus *	ReturnStatus = `NULL`
	)

Creates a new volume light dependency graph node and adds it to the dependency graph.

If the UIvisible parameter is true, the new node will be connected to the light classification node (which allows the UI to recognize the node as a light) and added to the default light list. If UIvisible is false, the node will be created in isolation.

If wantTransform parameter is false ( which is by default ), the new shape node is created under the specified parent and no transform node is created. If the specified parent is null, then no shape node will be created.

The light node is added to the current model, under the specified parent.

Returns: MObject representing the new dependency node.

Status Codes:

MS::kSuccess operation successful
MS::kInsufficientMemory ran out of memory
MS::kNoModelActive no model is currently active
MS::kLicenseFailure application not licensed for attempted operation
MS::kFailure the new node could not be added to the model, or the function set could not be properly initialized with the new object.
