Effects of Transforming the UVW Map Gizmo
Mo ving the gizmo changes the center of projection
and affects all types of m apping. Rotating the
gizmo changes the orientation of the map, which
affects all types of mapping. Uniform scaling does
not affect spherical or shrink-wrap mapping.
Non-uniform scaling affects all ty pes of mapping.
If you scale a gizmo smaller than the geometry,

no effect on the map type in use. Tiling based on
gizmo size is in addition to ti ling values set in the
Material Editor Coordinates rollout for the map or
the UVW Map modifier tile controls.

Manipulators for UVW Map
The UVW Map modifier has graphic manipulators
to help you adjust the mapping dimensions and
tiling when Real-World Map Size is off. When
Real-World Map Size is on, you can adjust
positioning only for the Planar and Box mapping
types.
Manipulators are visible and usable whi le
the Select And Manipulate button (page 2–15)
isactive. Thisbuttonisonthedefaulttoolbar
(page 3–685). When you mo v e the mouse over a
manipulator, the manipulator tur ns red to show
that dragging or clicking it will have an effect.
Also, a tooltip appears, showing the object name,
the parameter, a nd its value.
For more information on using the UVW Map
manipulators, see the Procedures section (page
1–925).

repeat. Tiled maps are useful for bricks on a wall,
or tiles on a floor. Rather than creating one large
map, seamless maps can be t i led to sur face a large
area without visible seams, to give the illusion of a
large map.
Tiling in the UVW Map modifier affects only the
objects that use this modifier. Tiling a map in the
Material Editor affects tiling on all the objects that
use the material.
Material and UVW Map tiling are multiplied. If a
