Global Motion Blur buttonEnable to use motion blur. Once enabled, specific Action object Motion Blur buttons can be enabled or disabled.

Phase fieldDisplays the frame that motion blur is based on (before or after the current frame). A value of -100 places the motion blur before while a value of 100 places the motion blur after. A value of 0 is centred, which evenly distributes the motion blur. The default value is 0.

Shutter fieldDisplays the duration of motion blur at each frame (essentially the number of frames that the shutter is open). Increasing this value does not increase the processing time.

Samples fieldDisplays the quality level of motion blur and the depth of field produced by the number of samples taken at each frame. Increasing this value causes the processing time to increase linearly and affects the quality of the depth of field.

The number of motion blur samples is multiplied by the number of anti-aliasing samples. To reduce the total number of passes made for each frame, reduce the level of anti-aliasing when motion blur is enabled.

TipYou can animate the Global Motion blur button, as well as the Phase, Shutter, and Samples fields. They can be found in the Channel Editor under the motion_blur folder.
