Simulating Motion Blur on a Still Object
You can add motion blur to an object that has no axis movement, by adding a second axis to simulate the motion.
To simulate motion blur on a still object:
From the View box, select Schematic.
From the Node bin, drag an Axis node to the schematic.
Press Shift and drag the original Axis node over the new Axis node.
Enable Motion Blur and animate the new axis with the desired motion.
