VrayPhysicalCamera Motion Blur Amount

Hi everyone! I've imported camera data from syntheyes as a VrayPhysicalCamera. I set it up as I wanted, except one thing - motion blur amount. I use "Movie Camera" type for vrayphysicalcamera, so there's only two parameters available which are "shutter angle" and "shutter offset", but I need "shutter speed" parameter to control motion blur amount.
So whould you change vrayphysicalcamera's motion blur amount?

Hi!

I always do motion blur in post, but 'Shutter angle' is kind of the shutter speed for movie cameras. Change that to affect motion blur.

Thanks for reply. But how do you apply motion blur in post? I'm using Ae, is there a special plugin for it?

You kick out motion vectors via the vray velocity render element. You use that pass in conjunction with, say, ReelSmart Motion Blur (RSMB).

Doing it this way is faster to render and fast to tweak in post, but be warned, it really doesn't look as good as vray moblur. If you can, use in-camera moblur. I've been starting to use in-camera on the last couple of jobs and have been pretty happy.
