Here you go try this for starters Gedd.
Everything looks good until we get to Velvet. In my experience 100% is far too strong 20% is probably a good starting point and Fall Off of about 15%. Velvet is used to simulate fine hairs we have on our bodies.
Subsurface Scattering; US2 does this differently from HSS.
Subsurface Colour; US2 255,255,255 White
Subsurface Refraction; I set to 1.39 given that is what IOR real skin is. But I am not 100% sure on this as we have an IOR setting toward the top of the settings. I have set both to 1.39 but I have not seen any noticeable difference.
Subsurface Scale; Is how thick the skin is IMHO 4 is too thick I always set this to 1.
Subsurface Group; Is used for grouping SSS effects so if you want to use different SSS settings on the Ears fpr example then you can assign a different number so the render engine will treat that area differently than the other group and render accordingly.
Subsurface Shading Rate; is ok at 32 for most images. If using IDL then think about increasing if you get speckling even with the Advanced Render Shading Rate is to .2 or lower.
Subsurface Scatter Colour; This is where we put the SSS colour when it comes to US2. So in this case it would be 116,44,29 (I think that is what the HSS colour is as I can hardly see the image is too small and I saved it to my Computer too. ).
Subsurface Scatter Strength; is something I am still trying to understand. Hence why I suggested using one of the Skin presets that come with US2 to see what he set them to. You can always Undo.
Subsurface Scatter Absorption; Colour and Strength same advice as above. One of the default colours with the presets is a dark yellow/orange. I think this is what colour light gets when absorbed in to the skin, what is left over from the light getting scattered back out though the red blood in our skin.
Translucency; Is why too high at 100%. Try 15% to start with.
Hope this helps
