Fields
clamp
Sets the maximum length, as a fraction of the screen's full resolution, that the velocity resulting from Camera rotation can have. Lower values will improve performance.
Declaration
[Tooltip("Sets the maximum length, as a fraction of the screen's full resolution, that the velocity resulting from Camera rotation can have. Lower values will improve performance.")]
public ClampedFloatParameter clamp
Field Value
Type | Description |
---|---|
Clamped |

intensity
Sets the intensity of the motion blur effect. Acts as a multiplier for velocities.
Declaration
[Tooltip("The strength of the motion blur filter. Acts as a multiplier for velocities.")]
public ClampedFloatParameter intensity
Field Value
Type | Description |
---|---|
Clamped |
See Also
mode
The motion blur technique to use. If you don't need object motion blur, CameraOnly will result in better performance.
Declaration
[Tooltip("The motion blur technique to use. If you don't need object motion blur, CameraOnly will result in better performance.")]
public MotionBlurModeParameter mode
Field Value
Type | Description |
---|---|
Motion |

quality
The quality of the effect. Lower presets will result in better performance at the expense of visual quality.
Declaration
[Tooltip("The quality of the effect. Lower presets will result in better performance at the expense of visual quality.")]
public MotionBlurQualityParameter quality
Field Value
