536 Chapter 8: Modifiers
When you first pick a path, the object is deformed
by the path based on the offset distance b etween
the f irst vertex in the path and the object’s location.
Thus, as you adjust the Percent spinner, for
example, t he result will be distor ted depending on
the offset distance.
Impor tant: Using the Move To Path button applies
a transform to the object that’s not removed if you
later remove the Path Deform binding from the object.
However, you can
undo (page 1–93) the transform
immediately after it’s been per formed.)
Note:
If the Auto Key button is on when you
perform Move To Path, transform keys are created.

The Subdivide (WSM) modifier is similar to the
object-space
Subdivide modifier (page 1–829) ,
and has the same parameters. In the world-space
version of Subdivide, the size limit is on the
mesh after it is transformed into world space
coordinates.
Surface Mapper Modifier ( World

Make a selection. > Modify panel > Modifier List >
World-Space Modifiers > * Surface Mapper
The Surface Mapper (WSM) modifier takes a map
assigned to a
NURBS (page 1–1079) surface and
projects it onto the modified object or objects.
Surface Mapper is especially useful for seamlessly
applying a single map to a group of surface
sub-objects within the same NURBS model. You
can also use it for other kinds of geometry.
The NURBS surface’s map is projected onto the
other geometry in the direction of the NURBS
surface’s normals, or opposite the normals if the
modified object is on the other side of the NURBS
surface.
Procedure
To use the surface mapper world-space modif ier :
1.
CreatetheNURBSsurfacetouseforprojection,
and transform it so it wraps the objects you
want to map.
2. Use the Material Editor (page 2–1253)
to assign a mapped material to the NURBS
surface.
3. Select the objects you want to map.
4. Use the Material Editor to assign the
same material to the objects you want to map.
5. Apply the Surface Mapper world-space
modifier.
6. In the Parameters rollout, turn on Pick NURBS
Surface, and then click the NURBS projection
surface in a viewport.
