Is it just the bright edge of fresnel you do not like ? or does maxwell still fail the test with the torus? ( is that mxm available)
The issue I have described only relates to fresnel in as far as the effect tends to be the most visible at grazing angles, because, for most materials, that's where reflectiveness is the strongest. Look at the examples on page 4 for a direct comparison. If the additive approach to coatings had no side effects, these two images should look identical.
