in the 0.5-20 range. Lower values decrease
antialiasing; higher values increase it.
TheBlurOffsetparameteradjuststheimage
before antialiasing Blur is applied. If all you
need is antialiasing, leave Blur Offset at its
default of 0.0.
To make a map image fuzzier:
• Onthemap’sCoordinate’srollout,increasethe
Blur Offset value.
Blur Offset is a very strong parameter. The Blur
Offset spinner has increments of 0.001 Values
greaterthan0.1arelikelytobetoohigh.
To make a map image sharper:
• On the map’s Co ordinates rollout, decrease the
Blur Offset value to a value below 0.0.
The negative Blur Offset va lue sharp ens the
image.

Mappi ng l ist—Options vary depending on cho ice
of Texture or Environ mapping:
•
Explicit Map Channel—Uses any m ap channel.
When selected, the Map Channel field becomes
active, and you can choose any channel from
1 to 99.
•
Ver tex Color Channel—Uses assigned vertex
colors as a channel. See
Editable Mesh (page
1–984)
for details on assigning vertex color.

•
Planar from Object XY Z—Uses planar mapping
based on the object’s local coordinates
(disregarding the pivot point location). For
rendering purposes, planar mapping doesn’t
project through to the back of the object unless
you turn on Show Map On Back.
•
Planar from World XYZ—Uses planar mapping
based on the scene’s world coordinates
(disregarding the object’s bounding box). For
rendering purposes, planar mapping doesn’t
project through to the back of the object unless
you turn on Show Map On Back.
•
Spherica l Environment, Cylindrical Environment,
Shrink-wrap Environment—
Project the map
into the scene as though it were mapped to
an invisible object in the background. See
Environment Map (page 3–1028)
.
•
Screen—Projects as a flat backdrop in the scene.
Show M ap on B ack —When on, planar mapping
(Planar from Object XYZ, or with the UVW Map
modifier)projectsthroughtorenderontheback
of the object. When off, planar mapping doesn’t
render on the object’s back. Default=on.
This toggle is available only when Tiling i s off in
both dimensions. Its effect is visible only when
you render the scene.
Note: In viewports, planar mapping always projects
to the back of the object, whether Show Map On
