Question Depth Pass doesn't work with matchmoving camera


I haven't been able to solve a depth pass rendering problem. Thus, I hope to find any clue or better solution..
I tried to create Depth passes in a couple of different ways. However, there is just black and white image whenever I render using an imported camera from bojou.
I used bojou for motion tracking, then I exported the camera to Maya.

The depth pass is rendered correctly using Maya perspective camera. It is fine as well when I created a new camera and doing a render with it.

For the Depth pass, I use render layer with luminance Depth presets and adjust the out color shader Old Min and Old Max.

I cannot find what went wrong with that imported camera.. anyone have any idea?

Thank you! Hope that I explained my problem here clearly..

in the worst case scenario, just create a new maya camera and copy the camera info / animation over.

Thanks! But, can you let me know how would you copy those camera's info to a new camera?
There might be some ways to do it, but I am not sure how to do that properly..

it will be easier to pinpoint what cause if you can put your maya file here. you can check those things though:
1. Does the imported camera have a parent.?
2. the imported camera's scale should be 1.
3. camera does not have a image plane attached.
4. render float (half or full)

One thing to check is whether or not there are any scale transforms on the boujou camera (or in the boujou camera group). Scaling cameras messes up clipping planes and zdepth.

Thank you so much !!! I am sorry for this weird issue. I could get the depth pass now. The problem before was with gamma correction value.
