Hello everyone
I am having problem with the dof and physical cam…
Could someone explain how I can achieve the same DOF as with the default cam?
Does the DOF with physical cam work in meters) Does it have to be in milieters?

Thanks

In a real camera the DOF is controled by the F-Number, the same thing happen in V-Ray. The F-Number control the DOF, but you have to keep in mind that the F-Number also control the exposure. SO the idea is to keep the EV when you are working with DOF and physical camera. Lower F-Number produce more DOF effect while larger number produce less DOF.
I found the following tutorial very useful to explain what I’m saying. It is for 3ds Max, but the same concept apply to Rhino.
