How can one make a render pass with black and white data to display depth of field based on the Settings > Camera dof settings?
I want to blur or defocus in the compositor, similar to the way it is done with the Z pass but with a more accurate dof information that is based on a target, as opposed to distance away from the camera.
I tried to fiddle with the settings in a new Render layer, overwriting the material, but I have been unable to achieve a render pass effect that outputs something useful.
