Importing Animation
You can only import camera animation from a 3D
Studio file. Lightscape uses Catmull-Rom cubic
Bézier spline construction between provided posi-
tion points. It linearly interpolates other information
(field of view and target point). Lightscape does not
currently support 3D Studio spline modifiers, such
as bias and tension.
A single 3D Studio file can have several animation
tracks. In such cases, Lightscape creates separate .la
files, named
filename 1.la, filename 2.la, and so on,
where filename is the name of the 3D Studio file. You
can only generate animation files with the stand-
alone command line utility
3ds2lp . Animation infor-
mation is ignored from within the Lightscape
application. For more information, see Chapter 15,
“Animation,” and Appendix B, “Batch Processing
Utilities.”
Import Keyframe Instances
This controls whether the Keyframe section of the
3DS file is used to import instances of geometry in
the 3D Editor section of the 3ds file. If it is enabled,
an instance is imported for each instance in the
Keyframe. If any geometry in the 3D Editor is not
referenced in the Keyframe, it will also be instanced
once. If it is not checked, the geometry is imported
as is without using the Keyframe. In most cases, you
should enable Import Keyframe Instances.
Importing Background and Fog
If the background in the 3D Studio file is a solid
color, that color is used for the background in Light-
scape. If the background is white, it is converted to
gray in Lightscape so that white lines are visible.
To change the line color in Lightscape, choose
File | Properties, and adjust the Wireframe color on
the Color panel. For more information, see Chapter
4, “The Interface.”
If fog is set in 3D Studio, the fog settings are
imported but turned off in Lightscape. For informa-
tion on setting fog in Lightscape, see “Setting Fog
Properties” on page 47.
Other background information, such as texture
mapping or environmental effects, is not
imported.
Stop on Translation Error
When importing files, some translation errors may
occur that could minimally affect the data in the file.
You can ignore these error messages when you
import a file or you can select the Stop on Transla-
tion Errors option to have the import process stop
when it encounters an error.
File Was Produced for/by 3DS MAX
There is a subtle difference in the way 3D Studio and
3D Studio MAX handle lights linked to cameras.
This option tells the importer which way to interpret
the data to produce the same result.
Importing a LightWave Scene
You can import a LightWave scene into your Light-
scape Preparation file.
