I am trying to generate an OpenEXR file based on the following procedure : Getting the depth of every pixel to the center of projection of the camera in Blender
I have tried to create a simple scene with a cube and a camera (default scene in blender) and the above procedure works well and I am also able to save the pass data in an open EXR file using the file output node in blender.
However, on downloading the demo files provided on the blender's website: https://www.blender.org/download/demo-files/
The OpenEXR file simply doesn't get created. I have tried with the classroom demo file as well as the architectural visualization file. The below are the screenshots that I tried with for the Architectural Visualization under the compositor window:
Are there any specifics that I am missing out on?
