Image Motion Blur group
You determine which objects have
image motion blur on page 7814 applied
to them by setting Image in the Motion Blur group of the Properties dialog
for that object. Image motion blur blurs the object by creating a smearing
effect rather than multiple images. It takes camera movement into account.
Image motion blur is applied after scanline rendering is complete.
