2 On the Default Scanline Renderer rollout, turn on Apply in the Object
Motion Blur group or the Image Motion Blur group.
■ For Object Motion Blur, set Duration, Duration Subdivisions, and
Samples.
■ Increase Duration to exaggerate the motion blur effect. Decrease it to
make the blur more subtle.
■ If Samples is less than Duration Subdivisions, the slices used are
selected randomly, giving a grainy look to the blur. If Samples equals
Duration Subdivisions, the blur is smooth. The smoothest blur results
from larger, equal values of these two parameters, but be aware that
this can slow down rendering by a factor of three to four.
■ For Image Motion Blur, adjust Duration and Apply to Environment
Map.
■ Increase Duration to exaggerate the streaking. Decrease it to make it
more subtle.
3 Turn on Apply to Environment map to have camera orbit movement
blur the environment map. This works only with Spherical, Cylindrical,
or Shrink-Wrapped environments.
4 Set other rendering parameters, and then click Render.
