Ifthesourcesceneincludesnestedexternal
references, using Include All can cause some
confusion if you are not careful about your tree of
scenes. Consider the following arrangement:
master.max (Include All) --> a.max (Include All) --> b.max
If you later open b.max, create objects, and save
it, then open master.max withoutfirstopening
and saving a.max, you won’t see the new objects
created in b.max.Thescenemaster.max is simply
reading a.max, and since a.max hasn’t changed,
the new objects aren’t present.
Automatic Upda te—When on, changes made
to externally referenced objects, controllers,
materials, and manipulators in the source scene
are automa tically updated in the master file as
soon as the source file is saved. There’s no need to
click Update. Default=off.
Note: You can change the state of Enabled, Include
All, and Automatic Update after a record is created.
Merge Transfor ms—When on, combines all objects ’
externally referenced transform controllers from
thesourcefileintothemasterfile. Thismeans
that the tra nsform controllers will be loaded in
the master file but will then no longer have a live
connection with the source f ile. This is useful if
you don’t require the live connection, and want
to alter the transform controllers in the master
scene without losing your edits upon Update.
Default=off.
To use Merge Transforms, you must turn on this
option before you add the XRef record (source) file.
Merge Materials—When on, combines all
externally referenced materials from the source file
into the master file. This means that the materials
willbeloadedinthemasterfilebutwillthenno
longer hav e a live connection with the source
file. This is useful if you don’ t require the live
connection, and want to alter the materials in
the master scene without losing your edits upon
Update. Default=off.
To use Merge Materials, you must turn on this
option before you add the XRef record (source) file.
When Merge Materials is on and there are name
conflicts b etween materials in the target scene and
materials in the XRef source scene (or between
materials in two XRef records), 3ds Max displays a
Duplicate Name dialog (page 2–1453) so you can
resolve the conflicts.
Merge Manipulators— When on, any manipulator
(page 2–27) applied to the XRef object in the source
file is combined into the scene. Manipulators are
applied to the XRef object and can be changed.
However, these changes have no effect in the XRef
source fi le. Default=off.
To use Merge Manipulators, you must turn on this
option before you add the XRef record (source) file.
Modifiers—Determines how modifiers from the
source file will be loaded into your master file.
Modifiers are not listed as XRef entities. To
see an XRef m odifier on the Modify panel, you
must use the Merge option. Otherwise, you have
the choice of either not merging the modifier
information at all (w ith the Ignore option) or
merging t he information with the object with the
XRef Modifiers option.

XRef—Modifiers are contained within the XRef
object and cannot be changed in the m aster
scene. When you load the external reference
file, you will see the results of the mo difier but
they will not b e listed separately from the object
on the Modify panel. Additional modifiers can
be applied to the XRef object, and will be a par t
of the scene; however, they w i l l not b e reflected
backtothesourcefile.
