Lightscape Preparation File General Panel 593
The Master Units are also used as t he display units
in the exported LP file.
Scale Factor—A scaling factor that is applied to
theentiremodel. Anypositiverealnumberis
accepted. Use this setting to globally adjust the
size of the exported model. Default=1.
If your scene uses realistic physical dimensions,
as it probably does if you use photometric lights,
then leave Scale Factor set to 1. If you didn’t create
your scene using realistic physical dimensions,
whichisoftenthecasewhenusingstandardlights
or generic units, you might have to adjust the
scene’s scale.
Model Size—Displays the X , Y, and Z extents of the
scene’s geometry using the current Master Units
and Scale Factor settings. T his can help you set up
the exported file if you need to change either of
these settings. Model Size does
not include lights
and cameras, which mig ht be outside the extents
of the renderable geometry.
Entire Scene and Selected Objects—These radio
buttons select whether all o bjec ts in the scene are
exported, or only selected objects.
Block Creation and Name—These settings a llow you
to select how blocks are created in the exported
LP fi le. Default=Group. The four possible settings
are:
•
Object—A Lightscape block is created for each
object. The name of each block is taken from
thenameofthefirstinstanceoftheobject.
If different instances of a single object use
different materials, a new block is created so the
proper material can be applied to the instance.
The blocks are then created in the LP file.
•
Group—A block is created for each object, as
w ith the Object option, and als o for each group.
The blocks are created in the LP file based on
the groups in which they are contained.
•
Single—Asingleblockiscreatedfortheentire
scene. All of the meshes of all of the objects
reside within this block. One instance of this
block is created for the LP file. When this
setting is chosen, the Name field is enabled.
You can enter the block name in this field.
Default=Thenameoftheexportedfile(withno
file name extension).
•
None—No blocks are created. All of the meshes
of all of the objects are created d irectly in the
LP file.
Tip: If you r scene uses object instancing, creating
blocks can reduce the file size of the exported LP
file, because the geometry of the object is exported
only once. You can also use groups to group lights
w ith the geometry that represents their fixtures.
This wil l make moving and changing lights easier
in Lightscape.
Layer Creation a nd Name—These settings a llow you
to select how Lightscape layers are created and
how surfaces and blocks are placed on the lay ers.
Default=Instance. The five possible setti ngs are:
•
Instance—A layer is created for each object
instance in the model, including lights. The
surfaces f or each instance are placed on their
own layer. T he name of the layer is the same as
thenameoftheobjectinstance.Thissettingis
very useful if you plan to import the Lightscape
solution back into 3ds Max, since the importer
can reconstruct the original objects.
•
Object—A layer is created for each object. All
surfaces in all instances of the object are placed
in the layer for t he object. The name of the layer
isthesameasthenameofthefirstinstanceof
the object.
•
Group—A layer is created for each object
and each group. All surfaces in all instances
belonging to a group are placed in the layer
for the group. All other surfaces are placed in
the layer for the object. T he name of the layer
isthesameasthenameofthefirstinstanceof
the object.
