Motion Blur effect simulates the blur of the objects based on its motion. When objects filmed by a camera are moving faster than the camera’s exposure time they are appearing as blurred on the edges. This can be caused by rapidly moving objects or a long exposure time. The effect itself is based on Motion Vectors buffer rendering which contains a objects pixels moving across the screen.
|Enabled||If checked, motion blur effect will be rendered.|
|Scale||The blur effect strength. Value 0 disabled is, while higher values increase the effect.|
|Sample Count||The amount of sample points used during motion blur rendering. It affects quality and performance.|
|Motion Vectors Resolution||The motion vectors texture resolution. Motion blur uses per-pixel motion vectors buffer that contains objects movement information. Use lower resolution to improve performance.|
Motion Vectors Debug
The editor supports rendering motion vectors visualization by checking the View -> Debug View -> Motion Vectors. You can use it to preview and debug motion vectors of your game objects.
Skeletal meshes support Per Bone Motion Blur that handles rendering the pixels motion for the animated model bones transformation changes.
