Motion blur added to rendering of an animated wheel as it speeds up and rolls forward
To render motion blur with the mental ray renderer, you must turn on ray
tracing (the Ray Trace parameter) on the Render Scene dialog > Renderer panel
>
Rendering Algorithms rollout on page 6118 .
The mental ray renderer uses a Shutter parameter to control motion blur. This
simulates the shutter speed of a camera. At 0.0, there is no motion blurring.
At 1.0, the maximum amount of motion blurring occurs. Values between zero
and one adjust the amount of motion blur. The closer to 1.0, the greater the
blurring.
You turn on motion blur and adjust shutter speed on the Render Scene Dialog
> Renderer panel >
Camera Effects rollout on page 6087 .
If you render using
shadow maps on page 7928 , then by default mental ray
applies motion blur to these as well. See the Render Scene dialog > Renderer
panel > Shadows & Displacement rollout on page 6114 .
TIP mental ray motion blur is not recommended for use with particle systems, as
this can increase rendering time considerably. Use a
Particle MBlur map on page
5729 instead.
