mental ray DOF to vray

[super gnu]

ive got a set of animated standard Max cameras. amongst other things, they have the MR dof active, with an animated F-stop controlling the strength of the effect.

is there any way to get vray to render this without redoing it for all the cameras?

Yes, you can enable DOF for Max Cameras from Camera Rollout:

According to the animation you could get the focus distance from the camera or you have to manually animate the Focus Distance Parameter.

i know i can use dof with max cameras, but i was wondering if i can get the dof strength from the "mr dof" f-stop setting on the standard camera, as it is animated on all my cameras, and i do not get the same result using the same f-stop values on the vray physical cam.

on a related note, if i disable exposure on the physical camera, it seems to stop the f-stop setting controlling the dof strength too.

What settings you are using?
I got very similar DOF results between V-Ray and Mray:

When Exposure is disabled the f-number, Shutter speed, and ISO settings will not affect the image brightness but the DOF strength should be affected.
