Motion Blur

Motion Blur is a common post-processing effect that simulates the blurring of an image when objects filmed by a camera are moving faster than the camera’s exposure time. This can be caused by rapidly moving objects or a long exposure time. Motion Blur is used to subtle effect in most types of games but exaggerated in some genres, such as racing games.

Motion blur on a camera that rotates very fast

Properties

Property	Function
Shutter Angle	The angle of the rotary shutter. Larger values give longer exposure therefore a stronger blur effect.
Sample Count	The amount of sample points, which affects quality and performances.

Performances

Using a lower Sample Count will lead to better performances.

Known issues and limitations

• Motion blur doesn't support AR/VR.

Requirements

• Motion vectors
• Depth texture
• Shader Model 3
