Problem with fibermesh vector displacement.

Hey.
I’m having trouble with fibermesh vector map displacement in 3DS Max. I have made sure that all my export settings are correct and I’m certain that all of my settings are correct in 3DS Max but when I hit render it just renders the base ploys from the fibermesh but no displacement. I have made sure that the base ploys have a few subdivisions set at render time so that the displacement map has something to extrude bu nothing is happening!
i was wondering if any knows of any bugs in zbrush regarding this issues and if there is a way around it?

anyone?
