Shockwave 3D Scene Export Options Dialog 631
when exporting just the animation in a scene;
otherwise, the W3D file will not work correctly
with Director.
Texture map resources—Exports al l texture maps
associated with all objects supported by the
exporter to t he Shockwave 3D file. Texture
maps in Shockwave 3D are bitmap images or
2D procedural maps, such as Tile and Gradient
Ramp. All bitmap images used in 3ds Max are
transformed by Shockwave 3D into streaming
JPEG images.
Note: The terms "Texture," "Map," and "Texture
Map" are used interchangeably. If this option is
turned off, models w ill be untextured w hen first
loaded into Director, because they will have no
texture information (despite their being visible
and fully shaded in the preview window). Once
textures are assigned to the proper shaders with
Lingo, the models will look properly textured.
Shader s—ExportsallshadersintheShockwave
3D file. Shaders are the highest-level entities
that describe surface properties. They bear no
relationship to the shaders used in 3ds Max.
Shockwave 3D does not dist ingu ish among Blinn,
Phong, Anisotropic, or any other shader algorithm
that determines the rendered look of m aterials
andmaps. OnlyGouraudshading,whichis

and
material resources
.
Note: The Shaders option should be used in
conjunction with the Texture Map Resources
and Material Resources options. If this option
is turned off, models wil l be inv isible when first
loaded into Director, because they will have no
shading information (despite their being visible
and fully shaded in the preview window). Once
shaders are assigned to the models with Lingo
(Director’s scripting language), the models will
become visible and look properly shaded.
Enable Toon and SDS—When turned off, this
option prevents the writing of geometry data used
bysomeofthemoreadvancedShockwave3D
technologies, and thus reduces the overall file size.
If turned off, Toon and Subdivision Surfaces (SDS)
data is not included in the export file, which means
that the Toon and Subdivision Surfaces modifiers
cannot be applied to the model in Director. A
model missing this geometry data can be used w ith
all other Shockwave 3D technologies, however.

Note: There is no way to tell if a W3D file was
exported with this option enabled or disabled
until you try to apply the Toon or SDS modifiers
in Director . For this reason, if you turn off this
option, use a special naming convention to
indicate that a model doesn’t have the Toon or SDS
data in it.
Light r esources—E xports all lights in the scene to
the Shockwave 3D file.
Turning this option off doesn’t do anything unless
the scenegraph hierarchy option is also turned off.
The only time you should turn this option off is
when exporting just the animation, geometry, or
texture data in a scene.
Cam era—Determines the viewpoint used for the
scene in Director. This option defaults to Active
Viewport, but if any cameras exist in the scene,
you can choose one from the drop-down list.
Note: In order to preview or export an animated
camera, you must select that camera from the
list. Selecting Active Viewport w ith an animated

Compression Settings group
The Shockwave 3D file contains all scene assets
in a proprietary compressed and streaming
format. You can control the order in which data
streams with the user properties. T he amount
