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 m aterial mapping. Default=on.
Auto Reflect/Refract and Mirrors—Ignores
automatic reflection/refraction 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, Mult iple Data.) Depending on the
CPU (or CPUs) of your system, SSE can improve
render time. Default=off.
Antialiasing group
Antialiasing— Antialiasing (page 3–1001)
smoothes the jagged edges that occur along the
edges of diagonal and curves lines when rendering.
Turn off only when you are rendering test images
and greater speed is more important than image
quality.
Turnin g off Antiali asing d isable s t he Force
Wireframe setting. Geometry renders according
to the material assigned it even if Force Wireframe
is turned on.
Turning off Antialiasing also disables
render
elements (page 3–126)
. If you need to render
elements,besuretoleaveAntialiasingon.
Filter drop-down list—Lets you select a hig h-quality
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.
The following table describes the available
antialiasing filters.
