Motion blur direction with Physical Camera

I’m working with m-blur and using the physical camera and I cannot figure out if there is a way to alter the direction of the blur.

I am finding that the blurs appear to be streaking ahead of the objects, and while it may be realistic depending on the shutter type etc., it’s not the expected direction and does not look right, at least in this case. Any way to change it for the physical camera?

I think you can alter the interval center or bias (forget which one now) and do this with the default cameras through the Camera rollout, but it does not seem to affect the physical camera.

Thanks in advance for any help.

What kind of camera are you using? Movie camera or Video one?

I normally use the still camera but could not seem to change it using the other one’s either, but I am not very clear on how they works comparatively.
