Inter face
Options group
Mapping—Turn off to ignore all mapping
information to speed up rendering for tests.
Affects automatic reflections and environment
maps as well as material mapping. Default=on.
Auto Reflect/Refract and M irrors—Ignores
automatic reflection/refrac tion maps to speed up
rendering for tests.
Shadows—When off, cast shadows aren’t rendered.
This can speed up rendering for tests. Default=on.
Force Wireframe—Set to render all surfaces in the
scene as wireframes. You can choose the thickness
of the wireframe in pixels. Default=1.
Enable SSE—When on, rendering uses Streaming
SIMD Extensions (SSE). (SIMD stands for Single
Instruction, Multiple Data.) Depending on the
CPU (or CPUs) of your system, SSE c an improve
render time. Default=off.
Antialiasing group
Antialiasing—Antialiasing (page 3–907) smoothes
the jagged edges that o ccur along the edges of
diagonal and curves lines w hen rendering. Turn
off only when you are rendering test images and
greater speed is more important than image
quality.
Turning of f Antial ias ing dis ables the Force
Wireframe setting. Geometry renders according
to the material assigned it even if Force Wireframe
is turned on.
Turning off Antialiasing also dis ables render
elements (page 3–130). If you need to render
elements,besuretoleaveAntialiasingon.
Filter drop-down list—Lets you select a high-qualit y
table-based filter to apply to your rendering.
Filters are the last step in antialiasing. They work
at the sub-pixel level and allow you to sharpen
or s often your final output, depending on which
filter you select. Below the controls in this group,

the filter and how it is applied to your image.
Tip: Render Region and Render Selected give
reliable results only when rendered with the Area
filter.

antialiasing fi lters.
