Ohh I'll have to take a look into that.
In my experience, a diffuse depth of 16 is the maximum at which the brightness will increase. Anything more than that is pretty much useless and just increases render time for no reason.
When you light your scene with only an HDRI its usually not necessary to go above a depth of 8 as there is more than enough light coming from everywhere. Also, when you increase the diffuse depth,
you will find that sometimes parts of your skin will look too bright or too saturated, you probably need to adjust them via color correction node.
I am currently working on a "non random walk" skin shader because Octane has so many problems when working with Random Walk, and especially in specular material, that I am willing to take a cut
at the realism to spare me the hassle.
