physical camera and frame stamp

When I add the camera variable to my frame stamp, it just says unknown instead of the camera view I’m rendering. Does the frame stamp recognize the vrayphysical camera as a “camera?” How can I make it work? i just don’t want to have to type it in each time…
(oh yeah, latest version of vray and max, all 32 bit…)

Thanks, JR

Are you using the V-Ray VFB?
