I've noticed some visual inconsistencies between the saved file outputs between 3ds max and the CIE when using the exact same sharpening values. This only happens when the images are saved with sharpening enabled, they both look the identical when they are in the VFB, and they are both identical when sharpening is disabled.
Files produced in 3ds max produce a dark outline when compared to files saved from the CIE.
I've attached some comparisons.
