Any idea if vray with 3ds Max produces the correct rpf velocity channels for using with Reel Motion Blur?

Any idea if vray with 3ds Max produces the correct rpf velocity channels for using with Reel Motion Blur?

I've seen the steps needed for producing the correct velocity channel with mental ray in 3ds max, and the added steps required.

We need to use Vray as it has a stereoscopic setting that other render engines are missing, and can't use a stereoscopic plugin as we want to send the work onto an online render farm which wont support any of the 3rd party plugins.

As such we want to produce rpf files using vray (which will produce a split view for 3d) and also export the velocity channel which we can then use to add motion blur in after effects with the Reel Motion Blur plugin.

Many thanks for any tips.

Thanks

Jon
