This dialog is displayed when exporting a
Lightscape material (ATR) file. Material files
contain only the material definitions in the model.
You can load materials f rom a Lightscape material
file into an exist ing Lig htscape model.
Inter face
Entire Scene and Selected Objects—These radio
buttons choose whether all materials in the scene
are exported, or only those materials used b y the
selected objects. Default=Entire Scene.
Don’t S ave Tex ture Data —Prevents textures from
being exported with materials.
Avera ge Textur e Color—Selects the material color
the exporter will use for texture-mapped materials.
If this option is off, the exporter will set the color
of texture-mapped materials to the diffuse color
of the 3ds Max material. If this option is on, the
exporter will set the color to the average color of
the diffuse map of a texture-mapped mater ial.
Relative Texture Paths—Selects whether or not
texture path names will be output as relative or
absolute paths. If this option is off, the exporter
will output absolute texture path names. If this
option is on, the exporter will output relative path
names. See
Using Relative Paths with Block and
Material Files (page 3–584)
for more information.

This d ialog is displayed when exporting a
Lightscape layer (LAY) file. Layer files contain only
the layer definitions in the model. You can load
layers from a Lightscape layer file into an existing
Lightscape model.
Note: The Lightscape exporter does not recognize
3ds Max scene layers, be cause it was written before
that feature was implemented.

Ent ire S ce n e an d Se le cted Object s—These radio
buttons select whether all layers in the scene are
exported, or only those layers used by the selected
objects. Default=Entire Scene.
Layer Creation a nd Name—These settings allow
you to select how layers are created and how
surfaces and blocks are placed on the layers.
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
the name of the 3ds Max instance of the object.
This setting is very useful if you pla n to import
the Lightscape solution back into 3ds Max,
since the importer can reconstruc t the origi nal
objects.
