LS Mesh Modifier
Select a Lightscape mesh objec t. > Modify panel >
Modifier List > LS Mesh
The LS Mesh modifier refines a Lightscape mesh
object.
When a Lightscape scene is imported into 3ds Max,
themeshproducedbyLightscapedoesn’tcontain
the refinements that Lightscape introduced
to improve the lighting. This information is
keptandusedbytheLightscape material (page
2–1604) while rendering. This modifier will add
theserefinementstotheLightscapemesh. In
conjunction with the LS Colors modifier (page
1–550), this modifier can be used to produce
meshes suitable for game engines.
The refinement stored in a Lightscape mesh is
hierarchical. When a polygon is refined, it is
broken in to four smaller polygons. These polygons
canthenberefinedfurther. Apolygoninthe
refinement has a depth from the original polygon,
which is the number of refinements needed to
get from the original polygon to the polygon in
question.

of polygons in the result by limiting the depth to
which the mo difier will descend, or by lim iting the
size of polygons that will b e refined.
You can apply the LS Mesh modifier to a Face
sub-object selection of a Lightscape mesh object.
In this case, only the selected faces will be refined.

Limit subdivision size—Whenthetoggleison,the

Whenthetoggleisoff,thenthemeshmodifierwill
refine polygons to any size. The size is a length in
the current view units. Polygons smaller than that
size squared will not be refined by the modifier.
Default=off, 19.685 units or 0.5 meters.
MapScaler Modifier (Object Space)
Select an object. > Modify panel > Modifier List >
Object-Space Modifiers > MapScaler
The MapScaler (OSM) modifier works in object
space to maintain the scale of a map applied to
an object. This lets you resize the object v ia its
creation parameters without altering the scale of
the map. Typically, you might use this to maintain
thesizeofamapregardlessofhowthegeometryis
scaled, if you change the object s ize by adjusting its
creat ion parameters. However, if you use a Select
And Scale tool to change the object size, the map
scales along w ith the object.
To maintain the scale of the map regardless of how
the object is resized, use the MapScaler (WSM)
modifier (page 1–551).
