Error Dialog (Lightscape Import) 623
See Luminaires and Photometric Lights (page
3–611)
for details of how luminaires are converted.
The remaining options in the Lights group are for
converting imported lights into standard lights.
They are unavailable unless you turn off Make
Lightscape Lig hts.
•
Automatic Intensity Calculation—The intensity
of each standard light is based on the intensity
of each Lightscape light. This option is chosen
by default.
•
Max imum Light I ntensity S ca le—The intensity
of each standard light is based on the intensity
of the Lightscape light divided by the specified
value. When this option is chosen, you can
enter the constant value in the field to the right
of the radio button. The value is in candles.
Default constant=12000.
This opt ion is useful when you import a
solution generated from a 3ds Max scene with
standard lights. If you used the Maximum Light
Intensity Scale option when you exported the
scene, this option will create li ghts with the
same intensit y as the original 3ds Max scene.
•
Light Intensity at Distance—The intensity of
each standard light is calculated by matching
the brightness of the standard light and the
brightness of the Lightscape light at a given
distance from the light. When this option
is chosen, you can enter the distance in the
field to the right of the radio button. The
value is in feet unless you specify meters (m).
Default=0.208m.
This opt ion is useful when you import a
solution generated from a 3ds Max scene. If
you used the Light Intensity At Distance option
when you exported the scene, this option will
create lights with the same intensity as the
original 3ds Max scene.
Use Attenua ti on—When on, the standard lights use
range attenuation. When off, the standard lights
are not attenuated. Default=on.
Note: The range attenuation limits are always
calculated,regardlessofthisoption’ssetting.
Pr es erv e S po tl i ght Ang les —When on, the hotspot
angleissettotheLightscapebeamangle.When
off,thehotspotangleissetsothestandard
spotlight distribution is closer to the Lightscape
light’s distribution. Default=on.
Leavethisoptiononifyouareusing3dsMaxfor
modeling only, and Lightscape for rendering. Turn
this option off if you want Lightscape and 3ds Max
rendering to be similar visually.
Er ror Dialog (Lightsca pe Impor t)
TheLightscapeimporterwilldisplayanerror
dialog when errors are found while merging
radiosity or i llumination maps into an existing
scene.
The e rrors that can be displaye d in the dialog are:
• Radiosit y data for [
objec t ]couldnotbe
merged.
The radiosity data for the specified object
couldn’t be merged. This can happen if the
object has been deleted, or if the faces of the
object have changed. The importer will not try
to import illumination maps if the radiosity
data cannot be merged.
• [
Fa ce -ma te rial ]: [ obje ct -materi a l ](
[
sub-m ateria l ] ): Could not be cloned.
The material named
face-material couldn’t
be cloned to add the illumination map. This
error is not expected, and usually indicates
that the system doesn’t have enough memory
to make a copy of the material.
Face-material
is assign ed as a sub-material of the material
