• Object—A layer is created for each 3ds Max
object. All surfaces in all instances of the object
are placed in the layer for the object. The name
ofthelayeristhesameasthenameofthefirst
instance of the object.
•
Group—A layer is created for each 3ds Max
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. The name of
thelayeristhesameasthenameofthefirst
instance of the object.
•
Single—Asinglelayeriscreatedandallsurfaces
are put on that layer. When this setting is used,
Name is enabled. You can enter the name of the
single layer in this field. The default name is the
base name of the exported file.
•
Mater ial—A layer is created for each exported
material. Surfaces are assigned to layers based
onthematerialassignedtothesurface.
Don’ t allow Lightsca pe to change geometry—When
this is on, flags are set to prevent Lightscape from
modifying the geometry when it is initialized to
start t he solution.
Note: This option is available only for recent
patches of Lightscape. The most recent patch is
available at f

patched Lightscape, you can use the new controls
Preserve Polygons and Condition Polygons. These
are located on the Layer Table Context menu.
Turning on Preserve Polygons preserves the
geometr y layout in the LP file; it is the Lig htscape
counterparttoDon’tAllowLightscapeToChange
Geometry in the LP exporter. Turning on
Condition Polygons restores the behavior to the
default for the c urrently selected layers.
Ex port Li ghtscape Par ameter File
Dia log
This d ialog is displayed when exporting a
Lightscape parameter (DF) file. Parameter files
contain the units and processing parameters
for the model. You can lo ad par a meters from
a Lightscape Parameter file into an existing
Lightscape model.
Interfa ce
Master Units—Specifies the units used by the
scene, so Lightscape can use them as well. To see
which units the scene is currently using, choose
Customize > Units S etup. If Master Units doesn’t
match the units spec ifie d in the Units Setup dialog,
Lightscape might give unrealistic results.
If your scene uses generic units, you wi l l have to
convert to real-world units for Lightscape to u se.
Inthiscase,youmightalsohavetoadjusttheScale
Factor . The Model Size display can help you do so.
The Master Units are also used as the display u nits
in the exported DF file.
Scale Factor—Gives a scaling factor applied to the
entire model. Any posit ive real number is accepted
and the default is 1.0. You can use this setting to
globally adjust the size of the exported model.
Model Size—Displays the X, Y, and Z extents of the
scene’s geometry using the current Master Units
