Import Lightscape Solution Dialog 621
Options in the Lights group of this dialog,
described below, specify how the importer imports
lights.
Sunlight—Imports a directional light that
duplicates the color and direction of the sun.
Default=on.
Background—Imports the current background
color in Lightscape. Default=on.
The default background color in both Lightscape
and 3ds Max is black.
Layers that are off—When on, imports objects
on Lightscape layers that are off. The objects are
imported as hidden objects. Default=off.
Note: Layers that are on are always imported.
K eep original Materials—When on, finds and keeps
the original 3ds Max materials that were exported
to create the Lig htscape materials in the solution.
When off, the importer creates a new 3ds Max
material for each Lig htscape material. See
Keeping
Your Orig inal 3ds Max Materials (page 3–584)
.
Default=on.
Entity Grouping group
Use these options to combine the imported
Lightscape geometry in various ways.
•
None—Imports each surface (flat area in
Lightscape that you can select) as a distinct
object.
•
All—Imports the Lightscape model as a single,
combined object.
•
By Layer—Imports each surface as an object,
and objects on the same layer are placed in the
same 3ds Max group.
•
By Material—Imports all Lightscape geometry
assigned the same material as a sing le object.

material name, along with the unique number
appended to the name.
•
By Material Within Layer—All surfaces that have
the same material and are on the same layer are
imported in a single group.
Radiosit y Mapping group
Controls the brightness and contrast of the image
displayed on your monitor and in renderings.
These controls also let you specif y the type
of radiosity mapping required for your scene
(daylight, exterior, or daylight and exterior).
Br ightness—Controls the brightness of the
displayed image on your monitor. The setting of
this control do es not affect the actual lighting levels
in the model. Typically, values range between
30 and 60. Default=the Brightness value in the
Lightscape model (you set th is on the Lightscape
Document Prop ert ies dialog: File > Properties >
Display tab).
Co ntrast—Controls the contrast between light
and dark regions in the model. Typically, values
range between 30 and 50. D efault=the C ontrast
value in the Lightscape model (you set this on the
Lightscape Document Properties dialog: File >
Properties > Display tab).
Daylight—When on, uses natural daylight when
calculating radiosity. D efault=the Daylight
(Sunlight + Sky Lig ht) setting in the Lig htscape
model(yousetthisontheLightscapeProcess
Parameters dialog: Pro cess > Parameters).
Ex terior—When on, uses exterior daylight when
calculating radiosity. Default=the
opposite of the
Daylight Through Windows And Openings Only
setting in the Lig htscape model (you set this on
the Lightscape Process Parameters dialog: Process
> Parameters).
Create Exposure Control—When on, creates a
logarithmic exposure control (page 3–293) for the
scene. Default=off.
When Make Lightscape Lights is turned on (in
the Lights group), this control is disabled and
