on importing Lightscape Solution (LS) files.
Mater ial Effects and Animated Shadows
Don’t Appear in R enderings
Processing direct illumination in Lightscape
contributes to the reduction of the time it takes to
render the scene in 3ds Max. However, because the
light was already cast in Lightscape, you will not
be able to use material effects such as opacit y or
specular mapping, or cast shadows from animated
objects.
Solution
Use the luminaire processing functions in
Lightscape to:
• Store direct and indirect illumination (the
defaultsetting)ifyoudon’tplantodoopacity
or specular mapping or use volumetric lights in
3ds Max.
• Process only the indirect illumination in the
cases where you want to use material mapping
such as opacity or specular mapping, or to cast
shadows from animated objects.
Wa rn in g: Don’t apply an edit mesh modifier to a
Lightscape mesh that has radiosity. Any geometric
changes destroy the mesh’s radiosity mapping.

Unusua l Patter ns A ppear on Surf aces
Thiscanhappenwhenyouimportadouble-sided
surface from Lightscape. Lightscape explodes
a double-sided surface into two back-to-back
surfacesatthesamelocation. Smallerrorsin
precision can prevent 3ds Max from consistently
selecting the correct surface, so the surfaces appear
to intersect one another .
Solution
Don’t use double-sided surfaces in Lightscape.
Instead, hide mesh faces that are facing away from
the view. In Lightscape, you can make a l l surfaces
single sided before you initiate your model:
1. Select all surfaces in the model.
2. Right-click and choose Orientation from the
menu.
3. Click the One-Sided button.
Refer to the
Lightscape User’s Guide for more
information.
TheImportedCameraViewDoesn’t
Match Lightscape
This can happen when you import a view that has
been scrolled in Lig htscape. Scrolling positions
the focus point of the view away from the center
of the window. 3ds Max cameras are not able to
display a view in this manner.
Solution
Avoid scrolling views in Lightscape. In Lightscape,
you can remove any scroll by:
1. Choose View > Setup.
