is installed with 3ds Max. For more information
about using the viewer, see the Autodesk DW F
Viewer help system.
Feature S uppor t with 3D DWF Ex port
• 2D and 3D splines. The Enable In Viewport
setting on the Rendering rollout (page 1–267)
does not need to be enabled in order to expor t
splines.
•3Dgeometry.
• Texture mapped materials with a diffuse map
channel, UV mapping channels, and material
IDs are published.
Note: Materials that have Use Real-World Scale
(page 2–1619) enabled display more accurately
in the DWF v iewer.
• Procedural materials are exported, but they are
only a rough approximation and will be very
low resolution. Real-World Map Size should
be turned off for objects that have procedural
materials assigned to them.
• Materials that have transparency are correctly
exported and their opacity values are
recognized by the DWF Viewer. Even as you
orbit the view, objects that pass b ehind other
objectsthathavetransparentmaterialsassigned
are still visible.
Limitations of 3D DWF Ex por t
Materia ls and Env ironments
• Environment backgrounds are not exported;
the DWF Viewer uses its own background color
setting.
• Environmentaleffectssuchasfogdonot
export.
• Materials using reflection maps such as F lat
Mirrordonotproduceareflectionwhen
exported.
• Two-sided materials are not supported.
However, you can get around this by tur ning on
Force Two Sided on the Render Scene dialog.
Note: Turni ng on Force Two- Side d affec t s
theentirescene. Thiscanslowdownthe
performance of the DWF Viewer because it has
to process the two-sided display of everything
in scene.
• Ma terials from third-party suppliers and
mental ray materials are not exported.
Objects that have unsupported materials
display in their diffuse color in the viewer.
Architectural Desktop mater ials are displayed
in their ambient color.
• Not all material parameters are exported, even
for supported materials. Therefore, materials
that are exported to the DWF Viewer m ay not
look as they do in a rendered image.
Lights
• You cannot export scene lighting.
Camera s and An im ation
•
Named camera views are exported. The
exporter creates a DW F v iew for each camera

Procedure
To expor t a 3D DWF f ile:
1.
Set up the scene in the ac tive viewp ort as you
want it displayed in the Autodesk DWF Viewer.
If you want to publish particular objects or
layers, make a selection set of those objects.
Hide those objects or layers you do not want
published.
