Coordinates Rollout (2D) 1629
When Use Real-World Scale is off
Offset (UV)—Changes the position of the map in
UV coordinates (page 3–1028) .Themapmovesin
relation to its size. For example, if you want to shift
the map its f ull width to the left, and half its width
downward from its ori ginal position, you enter -1
in the U Offset field a nd 0.5 in the V offset field.
UV/V W/WU—Changes the mapping coordinate
(page 3–967) system used for the map. The default
UV coordinates project the map onto the surface
like a slide projector. The VW and WU coordinates
rotate the map so that it is perpendicular to the
surface.
Tiling—D eterm ines the number of times the map
is tiled (page 3–1022) (repeated) along each axis.
Mirror—Mirrors (page 3–1022) the map
left-to-right (U axis) and/or top-to-bottom (V
axis).
Tile—TurnstilingonoroffintheUorVaxis.
When Use Real-World Scale is on
Of fs et (Width /Height)—Move the map
horizontally or vert ically along the w idth or height
of the object to which the material is applied. The
offset dista nce is relative to the lower-left corner
of the map.
UV/V W/WU—Changes the mapping coordinate
(page 3–967) system used for the map. The default
UV coordinates project the map onto the surface
like a slide projector. The VW and WU coordinates
rotate the map so that it is perpendicular to the
surface.
Size—Determines the real world width and
height of the map.
For example, if you scan a piece of marble that is
12” x 8” and then assign this image as the Diffuse
Map, you can type 12” (or 1’) and 8” as the Width
and Height. This ensures that the scale of the
marble is correct in the rendered scene.
Note: The default setting for the texture size can

Material Editor Options D ialog (page 2–1436).
Mirror—Mirrors (page 3–1022) the map
horizont a lly and/or vertically.
Tile—Turns horizontal and/or vertical tiling on or
off.
Note: If the Use Real-World Size switch is turned
off in the Material Editor, the Real-World Map
Size settings in modifiers like U VW Map or
for primitives like Box will not work. Likewise,
moving vertices at a sub-object level or sca ling
an object, in general, will not honor the Use
Real-World Scale settings.
