How to achieve sub-sampled motion blur?

[Fredrik Averpil]

Hi,

Let's say I've got an old fighter plane gunning away in the air with trail ammo, using a really shaky camera here adding lots of action to the scene.

With motion blur enabled, how can I make the trails look like corkscrews rather than straight lines, using V-Ray for Maya?
In Renderman I recall this was called sub-sampling (in the motion blur settings).

Geometry samples is the amount of actual geometry "snapshots" used.

In addition to the global geometry samples, you can also change the value on a per-object basis using the VRayObjectProperties node, since most likely not all of the scene needs higher geometry samples and they tend to take quite a bit of RAM.
