Motion Blur

Motion blur in Eevee is done by post processing the image after rendering.

The motion blur is really basic and just blurs the render results based on pixel velocity.

Nota

Object motion blur and deformation motion blur are still not supported. Only camera motion blur is supported.

Nota

Motion blur only works within the Camera View.
