Motion BlurBasic Tag
You can use this tag to apply motion blur to an object. Only works in conjunction with the enabled Vector Motion Blur option (and only when rendering in the Picture Viewer).
You can use this tag, in conjunction with the Physical Renderer’s motion blur, to define if an object should be rendered with motion blur (due to its change in position, rotation or size; this would reflect a No Deformation setting), with additional deformation blur (due to the effect of Deformers; Full Motion) or if any motion blur at all should be rendered.
Note that the object must be animated and moving at a reasonable speed for object motion blur to be seen; you must also render to the Picture Viewer — motion blur will not be shown when you render to the viewport.
