Fly through animation using stored shade maps

[king_max]

I'm working on an animation project, and wish to use the vray camera DOF and Mblur.
Is there a way to precalculate and store the shade maps without rendering the final images? (as when rendering the IRR and LC passes). I've tried a couple of combinations, but couldn't make it work.
When exactly does V-ray calculate the DOF effect?
