Truncated depth problem in depth images Using a Python rendering script, I rendered albedo, normal, and depth images.

Below are example an albedo and corresponding depth image. I am not getting why depth is truncated at some moment. Could anyone please advise how I can get the depth of the entire object?

For the rendering script, I referred: https://github.com/panmari/stanford-shapenet-renderer.
This may be an issue with the render distance. Can you try extending the camera distance and see if this helps?

With the camera object selected, increase its End clipping distance in Properties > Camera settings > Lens:
