Z AOV in Arnold render for very distant camera

Anonymous
Not applicable

I have a camera whose clipping planes are 260000 to 266000 (very far away to simulate a pure isometric scene). I am trying to output the depth information in a Z AOV (EXR format). When I adjust the exposure down in Photoshop, there is no point at which all of the depth information shows up, which I believe is due to the normalized value being between the camera and the far plane (too high a range). There are certain "blips" of information for different areas of the scene as I adjust the Offset slider, but at no setting that I can find is all the the information visible at once.  Does anyone known if this type of clipping range is even possible to output in Z AOVs? Thanks.
