I made a big post the other day on the Discord and it was about EXACTLY this sort of thing. Thank you for this, I really really appreciate the attention to detail you've added. Making something seem real can be about even the slightest details that even without in-depth examination, could end up leaving the person/character seeming JUST a bit cartoony still. Things like this plugin will go a long way to turning a 3D model into something that seems more lifelike.
It also only works if you use his SSS Person script. It does NOT work with the SSS Session plugin as that one continuously overwrites the shader.
My next update I'm going to try to add some code to detect his plug-in and brute force them to work together.
