The Surface Mapper (W SM) modifier takes a map
assigned to a N URBS (page 1–1078) surface and
projects it onto the modified object or objects.
Surface Mapper is especially useful for seamlessly
applyingasinglemaptoagroupofsurface
sub-objects within the same NURBS model. You
can a lso use it for other kinds of geometry.
The NURBS surface’s m ap is projected onto the
other geometry in the direction of the NUR BS
surface’s normals, or opposite the normals if the
modified object is on the other side of the NURBS
surface.
Procedure
To use the surf ace mapper worl d-space modif ier :
1.
CreatetheNURBSsurfacetouseforprojection,
and transform it so it wraps the objects you
want to m ap.
2. Use the Material Editor (page 2–1409)
to assign a mapped material to the NURBS
surface.
3. Select the objects you want to map.
4. U se 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.

Texture Surface dialog (page 1–1230).
