How to use Motion Blur

[paul_haase]

How does Motion Blur work?
I tryed it with a Cam with path constrain dosent work; tried to animate the cam on its own transform dosent work; tried with a recorded camera dosent work aswell.

Hi Paul

Sorry for the late reply. Motion blur is controlled by first enabling it from File>Advanced Scene Settings>Camera>Motion blur. And there you set exposure time rather than using the camera shutter speed. The motion blur in Vantage is "screen" based and treated as a post process effect rather than actual sub-frame ray-trace based. Motion samples are calculated based on how much a pixel has moved between frames rather than true calculated motion vectors for geometries during sub-frames, as V-Ray does, which will be more expensive and slow(a lot slower) to calculate.

Best regards,
Alexander
