Material effects t hat need 3ds Max light may
include specular mapping, opacity mapping,
and so on.
To turn off direct illumination storage, use
Lightscape. Select the lig hts that need to be on
in the 3ds Max scene. Right-click and choose
Luminaire Processing, then turn off the parameter
Store Direct Illumination.
K eeping Your S cene’ s Or iginal Materia ls
If you export a 3ds Max scene to Lightscape and
calculate a radiosity solution, you can have the
importer use your original 3ds Max materials
when you import the solution back into 3ds Max.
Do this when y ou export you r model:
• After you ha v e exported your scene, be sure
to save the MAX file. T he expor ter tags the
exported materials. If the scene is not saved, the
importer will not be able to find the materials it
needs to use.
Follow these steps when you import your model:
1.
Before importing the Lightscape solution, open
the MAX scene that wa s exported to create the
solution.
2. Import the LS file. In the Import Lightscape
Solution dialog, make sure the options Replace
Scene Contents and Keep Orig inal Materials
are both turned on.
3. Set the other import options you want to use,
then click OK to import the model.
Note: If the importer cannot find the 3ds Max
mater ial from which a Lightscape material was
created, it will create a new 3ds Max material.

Procedures
To specify a prefix for L ightsca pe objects:
When you import a Lightscape solution (LS)
file, you can specify a prefix to the name of each
imported object. This lets you easily identify and
group the Lightscape objects in your 3ds Max
scene.

To impor t selected Lightscape objects:
When y ou import a Lightscape Solution file, you
can choose which Lightscape objects to import.
• In the Import Lightscape Solution dialog, use

3ds Ma x s cene:
This procedure assumes you have already
established an existing scene, with radiosity.
1. Make backup copies of your existing 3ds Max
scene and your current Lightscape solut ion
(LS) file.
2. In your Lightscape solution, make your lighting
revisions and run the solution until y ou obtain
the desired result. Save the LS file.
3. In 3ds Max, import the LS file.
