[Max] General Discussion / How is Anima able to get motion blur to work with it’s 4D motion scanned people?

How is AXYZ’s Anima able to get motion blur to work with it’s 4D motion scanned people which have changing topology?
Corona isn’t meant to support mb with changing topology but how is Anima overriding this with functionality going down to very low shutter speeds.
I understand that if the shutter speed is high enough then corona will still be able to generate mb as there is enough information.
But, with anima you can take the shutter speed as low as you want and get no error. Taking a closer look, mb looks accurate up until a certain point but when it starts to get low it’s like a hack seems to kick in to replace and imitate normal mb? You can see how the geometry begins to crumple up in the buffer but it’s still very convincing even at 0.5! Pre generated motion vector data? If you take the shutter speed really really low then things start to get crazy.
Another interesting thing is that if I move the timeline slider while interactive rendering the meshes start to deform (see attached image) but this happens even if motion blur is off. I can even grab the actor in this state and convert to edit mesh before stopping interactive where it goes back to normal.
