Arnold + pflow, curved motion blur

[madsd]

Please support pr particle motion blur.

Your implementation currently is a linear construct, which makes it impossible to render particles with correct motion blur.

The issue has been reported multiple times and is a road blocker.

We know you work hard, but please escalate this issue to the top of the pile since it is a fundamental workflow killer.

This is the current situation, I greatly extended the motion trails to fully expose the weakness.

If this was working the motion blur trails on the gif would have been curly.

This is a major showstopper.

I feel this is somewhat more on the Arnold side of things more than 3ds Max, but this seems like a good place to keep track of it regardless. I heard they are planning to take a stab at this, so I'll move this over to accepted status.
