Use these tools to create and update XRef records.
Create XR ef R ecord from File—Launches an
Open File dialog so you can select the source file
foryourXRefrecord.Whenyouaselectafile,the
XRef Merge dialog (page 3–406) appears.
Any transform animation assigned to the source
objectscanbemergedalongwiththeXRefobject,
butitwillnotbeupdatedwiththesourceobject.
Note: If you w ant to maintain externally referenced
transforms,materials,andmanipulators,make
sure Merge Transforms, Merge Materials, and
MergeManipulatorsintheXRefObjectsdialogare
off before you click Create XRef Record from File.
Remove XRef Record—Deletes the highlighted
XRef record(s) after you confirm the action. All
entities associated with the highlighted record(s)
are removed from the scene.
Note: Once you have removed an XRef record, you
cannot undo this action.
Combine X Ref Re cor ds —Click to combine the
contents of more than one XRef record f rom the
same source file into one record. This is useful
when you want to clean up the organization of
your XRef records. Rather than having multiple
records of the same file, you can group all of the
objects, controllers, and materials f rom that file
underthesamerecord. Thisbuttonisavailable
only when you highlight two records that refer to
thesamefilenameandpath;bothrecordsmust
have identical settings. XRef records must refer to
thesamefilewiththesameXRefentities.Combine
XRefRecordsonlyallowsyoutoconsolidateallof
the entities of one file into one XRef record entry.
It does not allow you to combine the contents of
different files, even if the files have the same name.
Note: Nested externally referenced records cannot
be combined.
Update—Refreshes the contents of the
selected XRef record. If the objects, controllers,
materials, or manipulators referenced have
changed in the source scene, you will see these
changes in your master scene.
Note: The changes must be saved in the source
file before you see t hem in the master file. If you
remove externally referenced entities from the
master file using the Delete XR ef Entity button,
these entities will not be externally referenced
when you update the XRef record, even though
they continue to exist in the source scene.
Note: Reloading XRef items works correctly
even when an object in the source scene has been
renamed, or deleted and then re-created with
the exac t same name, including character c ase.
However,ifthesourcescenecontainsseveralnodes
with the same name, an XRef item corresponding
to a node w hose name is not unique in the source
scene mi g ht not necessarily resolve as you expect
duringtheupdateprocess. Forbestresults,
maintain unique names for all nodes in the source
scene.
Wa rn in g : IfyouupdateanXRefinascenewithradiosity
(page 3–51), probably this will invalidate the radiosity
solution. After you update the XRef, reset the radiosity
solution and then recalcu late it.
Merge In Scene—Converts all XRef entities of
the high lig
hted record into native (local) entities
in your master scene. The objects, controllers,
materials, and manipulators are no longer

your master scene. A prompt appears so you can
confirm the action. Since a merged XRef entity
