Hi, can anyone with this problem provide some example files, screenshot of their EXR save settings, and detailed instructions of how they are proceeding? Here or via support@corona-renderer.com. We've had one similar report in our support recently, but we were unable to reproduce it. It also seems that some applications treat EXRs different than other ones. From my experience Fusion (which is free) usually treats them correctly (or in other words - as one would expect).
