The objXRefMgr Core Interface provides access to the XRef Manager, and is the preferred way for working with XRefs in MAXScript. Scripts should not use both the methods in this interface and those exposed by XRefObject. The objXrefMgr coordinates all object xref additions and changes in a scene.

Available in 3ds Max 8 and higher.

You may find the following concepts useful when working with XRefs in MAXScript:

• Xrefs are organized by the file they come from, which is represented by an IXRefRecord object. For example, the objXRefMgr.AddXrefItemsFromFile() method returns this object. See the IXrefRecordMixinInterface for methods available from this interface.
• Individual Xrefs in an XrefRecord are held in IXrefItem objects. See IXRefItem MixinInterface for methods exposed by that interface.

Interface: objXRefMgr

Properties:

objXRefMgr.includeAll : bool : Read|Write

Get/set the state of the "Include All" checkbox.

Default is True.

Available in 3ds Max 2016 and higher.

objXRefMgr.enableUseLocalProxySettings : bool : Read|Write

When set to True, local proxy settings will be used.

Default is False.

Available in 3ds Max 2016 and higher.

objXRefMgr.recordCount: DWORD : Read

Returns the number of Object XRef records.

objXRefMgr.dupObjNameAction : enum : Read|Write

dupObjNameAction enums: {#prompt|#xref|#skip|#deleteOld|#autoRename}

Get/set the action to perform when duplicate names have been detected.

objXRefMgr.dupMtlNameAction : enum : Read|Write

dupMtlNameAction enums: {#prompt|#useXRefed|#useScene|#autoRename}

Get/set the action to perform when duplicate material names have been detected.

objXRefMgr.mergeTransforms : bool : Read|Write

Get/set whether to merge the transformation controllers of the Object XRefs. When set to true, the transform controllers will be merged into the main scene and will lose the live connection to the referenced file. Default is false.

objXRefMgr.mergeMaterials : bool : Read|Write

Get/set whether to merge the materials of the Object XRefs. When set to true, the materials of the referenced objects will be merged into the main scene and will lose the live connection to the referenced file. This option must be set before creating the Object XRef. Default is false.

objXRefMgr.mergeManipulators : bool : Read|Write

Get/set whether to merge the manipulators of the Object XRefs. When set to true, the manipulators of the referenced objects will be merged into the main scene and will lose the live connection to the referenced file. This option must be set before creating the Object XRef. Default is false.

objXRefMgr.mergeModifiers : enum : Read|Write

mergeModifiers enums: {#xrefModifiers|#ignoreModifiers|#mergeModifiers}

Get/set the handling of the modifiers of the Object XRef.

When the #xrefModifiers option is specified, the modifiers will be applied to the XRef Object before it is merged into the main scene and cannot be changed.

When the #ignoreModifiers option is specified, the modifiers from the referenced file will not be applied to the XRef Object.

When the #mergeModifiers option is specified, the modifiers from the referenced file will be merged into the main scene and can be manipulated, but will lose their live connection to the referenced file.

This option must be set before creating the Object XRef.

objXRefMgr.getAutoUpdate : bool : Read|Write

Get/set whether to update the Object XRefs automatically when the referenced source file has been saved.
