objectsinthemasterfile,intheXRefMergedialog,
enable Display Influences and select the object’s
influences. Objects that influence each other must
be referenced in the same record to maintain the
relationship.
Note: Render effects such as glow or flare are not
carried in XRefs. To use render effects from the
source file, merge them in using the Merge buttons
found in the En vironment And Effects dialog.
Pr ocedur es
To add an XRef object:
1.
Choose File > XRef Objects.
The XRef Objects dialog enables you to choose
to Merge Transforms, Merge Materials, and
Merge Manipulators.
Note: If you want to maintain externally
referenced entities (tr ansforms, materials,
manipulators, or modifiers), make sure Merge
Transforms, Merge Materials, and Merge
Manipulators are off and XRef Modifiers is
selected before you proceed to the next step.
Tip: Yo u c a n t u r n on IncludeAllontheXRef
Objects dialog before you click Create XRef
RecordFromFile. Thisincludesallobjects,
including influences, transforms, and materials,
and bypasses the XRef Merge dialog.
2. C lick the Create XRef Record From File
button in the XRef Objects dialog. The Open
File dialog appears. Choose the file you want by
high lighting it in the list, then click Open. The
XRef Merge Dialog ( page 3–406) appears.
If the Merge Manipulators toggle is off before
you click Create XRef Record From File,
manipulators applied to XRef objects are linked
to the (externally referenced) source file. In a
similar way, the Modifiers drop-down list gives
you three alternatives for how to handle object
modifiers.
If the Merge Materials toggle is off before you
click Create XRef Record From File, materials
applied to XRef objects are linked to the
(externally referenced) source file. If Merge
Materialsison,thematerialsaremergedwith
the master scene.
If the Merge Transforms toggle is off before you
click Create XRef Record From File, transforms
applied to XRef objects are linked to the
(externally referenced) source file and cannot
be keyframed in the master file. If Merge
Transfor ms is on,thetransformsaremerged
w ith the master scene and can be keyframed.
3. Select the objects that you’d like to appear in
your master scene as XRef objects.
You can choose as many as you want by holding
down the
Ct rl key and highlighting them in
the list. If the source scene has a lot of object
types you don’t need to include, you can filter
the list by using the List Types radio buttons.
UsetheAllbuttontoselectalloftheentries,the
None button to select no entries and the Invert
button to highlight the opposite of your current
selection. You can also choose to display
Influences and Select Influences.
4. The XRef record appears in the upper list of the
XRef Objects dialo g and has the same name as
its source file. The externally referenced entities
appear in the lower list, where an entity can
be either an object, a cont roller, or a material.
Make additional choices at this time if you like.
You can cont rol how the objects will update
(either automatically or on demand). Updating
is done at the XRef record level: all objects,
transforms, and materials f rom a single XRef
record are updated at the same time.
To substitute an XR ef object with a pr oxy object:
With proxy objects, you can avoid loading your
detailed mo del in memor y, and speed up the time
of test renderings.
