Adding Motion Blur and Depth of Field to a Scene
When the Motion Blur and Depth of Field (DOF) effects options are enabled,
you can set parameters to define how they will appear in your scene.
NOTE The software renderer must be enabled to apply Motion Blur and Depth
of Field effects.
To add Motion Blur to your scene:
1 Under Fx, select Motion Blur.
2 Under Rendering, enter the desired number of samples. A greater number
of samples gives a more realistic effect, but requires more processing time.
3 Set a value for Camera Shutter.
To add depth-of field to your scene:
1 Under Fx, select Depth of Field.
2 Set a value for Camera Aperture.
Description:Property:
Used with motion blur. The software calculates which sample
should be considered most important and makes it appear
brighter.
Importance
Sampling
Used with motion blur. Sets the length of time the shutter is open.
A larger number yields a slower shutter speed and a greater
amount of motion blur.
Camera Shutter
Used with DOF. Sets the size of the camera lens opening. In-
creasing the size of the aperture increases the zone of sharpness
in front of and behind the plane that the lens is focused on.
Camera Aperture
Enabling Z-Buffer Effects in Your Scene
You can enable the Z-buffer for your scene to create realistic spatial depth
effects. The Z-buffer calculates the spatial depth for each pixel in an image to
define which pixels are hidden by others.
