Hi,

Could someone please explain to me how Z-DEPTH is calculated and who controls it? I tried to figure out how it is working inside Mantra => Images => Extra image planes => (Pz), but i seem completely lost :? I used z-depth in Vray and i know that is controlled by the camera… I need to measure two distances from the camera. The first one is the point at which you want the DOF to start and the second to be the point at which you want the DOF to end. This will determine the grayscale value

Any Idea?

thanks man, this is actually working !
