XRef Scenes Dialog 413
Automatic—
When this check box is turned on, the
selected XRef scene is automatically updated w hen
its source scene is saved.
Update Now—Click this to update a selected XRef
scene when you’re not using Automatic (or when
several XRef scenes are selected and some of them
are not set to Automatic). When you click Update
Now, the XRef is updated to match the latest sa v ed
version of the source scene.
Display Options group
These options let you specify how the selected
XRefs are displayed in view p orts. These options
have no effect on the rendered scene.
Visible—Turn on or off to display or hide the
selected XRefs. This affects the visibility of the
XRef in the viewports only (not in renderings).
Note, a lso, that this behavior is different from the
“Enabled” check box. Turning off Visible does not
remove the XRef from memory.
Box—Turn this on to display the selected XRefs
as bounding boxes. Turn off to display the full
geometry.
Ignore group
This group box lets you specify categories that you
do not want included with the XRef scene. For
example, if you turn on Lig hts, the lights in the
XRef source scene are not included in the current,
target scene. You can switch these categories on
and off at any time, but if you Merge an XRef scene
while a categor y is turned off, that category of
objects will not be merged into the scene.
Lights—Turn this on to ig nore the lights.
Came ras—Turn this on to ignore the cameras.
Shapes—Turn this on to ignore the shapes.
Helper s—Turn this on to ignore the helpers.
Animation—Turn this on to ignore the animation.
All animation in the scene is disabled and the scene
appears as it would at frame 0 of the source scene.
Wa rn in g : Children of an ignored object are also ignored.
For example, if you have mesh objects linked as children
to a dummy object and ignore Helpers, then the mesh
objects are ignored as well.
Parent group
These con trols let you position and animate XRef
scenes within the current scene by binding the
XRef scene to a p arent object.
Parent Na me f i e ld —Displaysthenameoftheparent
for the currently selected XRef.
Bind—Click this, and then pick an object in
thecurrentscenetobecometheparentofthe
highlighted XRefs. Once an XRef is bound to a
parent object, the transforms of the parent are
inherited by the XRef. T hus, you can animate t he
XRef by animating the transforms of the parent.
Unbind—Click to unbind the highlighted XRefs
from whichever parent they’d been bound to.
BindingXRefstoobjectsissimilartolinking
objects, as performed with the L ink/Unlink
buttons on the toolbar.
If you Merge a linked XRef scene, converting it
to objects in the current scene, the objects in
the XRef scene become link ed children of the
binding parent. At this point, you could Unlin k
them (u sing the toolbar command), and they’ll
maintain their offset p osition to the p arent.
Clo se—Click to close the dialog.
