First off, I made one mistake: Thin Wall option to material shaders was only introduced starting with Octane 2019. You can read more about it here:
viewtopic.php?f=33&t=70971Essentially, it treats geometry as “infinitesimally small” so specular material does not produce any refraction. This option helped me out tremendously on a cosmetic component that had a clear plastic outer hull around the main inner jar. It allowed the logo to show through more clearly and gave better definition to the very edges of the object (probably not a fully unbiased render but it worked for me!).
As for Thin Layer – that is the same thing as Thin Wall but for the Specular Layer node (for some reason they call that option by a different name on the layer node).
