Maya Z-Depth Pass

#1

Hey everyone,
I am in urgent need of help with a camera issue. For some reason the z depth pass on my camera is rendering only a white silhouette. I have tested the z depth on a new camera in the same scene and it works just fine. It is specific to the camera but I cant figure out what is influencing it to render the white silhouette only. The camera settings for the old and new are almost identical other than the lens length and being anamorphic. Any clue what it could be?
