Motion blur enhances the movement of the sword.
Motion Blur applies an image motion blur (page
3–1049)
to your rendered scene by blurring
moving objects or the entire scene. Motion blur

by simulating t he way a real-world camera works.
A camera has a shutter spee d, and if significant
movement of objects in the scene, or of the camera
itself, occurs during the time the shutter is open,

Note: In addition, you must set motion-blur
characteristics for objects to be blurred using the
Object Properties dialog (page 1–117) .

The Motion Blur Parameters rollout contains the

Work with tra nsparency—When on, motion blur

When off, objects behind t ransparent objects
receive no motion blur. Turning off this toggle can
improve rendering speed. Default=on.
Duration—Specifies how long the "virtual shutter"
is open. When this is set to 1.0, the virtual shutter
is open for the entire duration b e tween one frame
and the next. The hi gher the value, the greater the
motion blur effect. Default=1.0.

Note: When additional Render Effects are

Depth-of-Field effect should be the last effect to
