#include <iInstanceMgr.h>

Class Description

Manages instances of objects, modifiers, transformation controllers Use this interface to work with object instances in a Max scene.

There are several criteria based on which two or more objects must be considered instances of each other. This interface abstracts the details of dealing with them and thus help client code focus on the specific tasks it needs to perform on object instances, rather than on the logic of finding them. Two or more objects are considered instances of each other if:

They are regular Max instances or references (their nodes reference the same DerivedObject)
Are part of the same style (this applies to Max objects resulted from importing a DWG drawing that contains style information. See IADTObjMgr for more information on styles.)
Represent instances of the same block (this applies to Max objects resulted from importing a DWG drawing that contains block instances. See IBlockMgr for more information on blocks.)

Automatic material propagation to instances of objects
When automatic material propagation to object instances is On, materials assigned to an object via all means (UI, maxscript, SDK) will be automatically propagated to all instances and references of that object. No user confirmation is be required. When Off, material assignments to an object won't get propagated to the object's instances and references. The material of an instance can be still propagated by calling the SetMtlOnInstances method. The initial value of automatic material propagation can be set through the AutomaticMtlPropagation setting, in the InstanceMgr section of the application's .ini file. When the application closes, the current value of this settings saved in the .ini file by the system.

pure virtual

Retrieves instances and references of an object.

Instances of styles and blocks are collected only if IADTObjMgr and IBlockMgr interfaces are available.

Parameters

[in]	source	The node of the object whose instances are to be retrieved. For an object with multiple instances, any of the nodes representing an instance can be specified here as a parameter.
[in,out]	instances	Collection of nodes representing the instances of source The collection is cleared before this method starts filling it in. The source node is also included in this collection since every object can be thought of as having at least one instance.

Returns: The number of instances found. There's always at least 1 instance found

virtual unsigned long SetMtlOnInstances	(	INode &	source,

Returns: The number of instances found.

[in]	tabConts	The controllers to be made unique.

Returns: true if at least one controller can be made unique.

virtual bool MakeControllersUnique	(	INodeTab &	tabNodes,
		Tab< ReferenceTarget * > &	tabConts,
		int	iMultiNodeOption = `INSTANCE_MGR_MAKE_UNIQUE_PROMPT`
	)		const

pure virtual

Makes the given transform controllers unique.

Parameters

[in]	tabNodes	The nodes the controllers are applied to.
[in]	tabConts	The controllers to be made unique.
[in]	iMultiNodeOption	Specifies the method to use when making controllers unique.
