VRay empty EXR size


If you render an empty frame from VRay for Maya 2016 the EXR size would be much bigger than if there is something in the frame (5 MB vs 80 kB). I suppose this is related to autocrop, the “exr/dataWindow” metadata is equal to frame size in case of an empty frame.

Is there a workaround with this issue? The first thing which came to my mind is to detect if any geometry exist in frame and create pixel-sise cube cube in the corner if not, but this is quite wired and not easy-to-implement solution.
