I have been doing alot of work with SSS lately, and thought I would share some settings that give a really natural look in ds4
(the tutorial can also be found here…with a larger picture: http://rawart3d.deviantart.com/art/Sub-Surface-Scattering-in-DS-306744678 )
1) Apply your diffuse colour (skin texture), but set it’s strength to 70%.
“70% ....but that means I will loose all my cool details”
Don’t worry…..we will add those details back later…trust me.
2) Your specular and bump (or displacment) settings are set like normal.
3) Turn on the velvet node, and set it’s colour to a light pink.
This will soften the light on your skin in the same way small body hairs would.
4) In the subsurface colour section you will attach your original skin mat again (bringing back some of the details you lost previously). But set the base colour of this to a very light pink, this will bring in the pinkish tones that lay below our skin, caused by all the blood in our body.
You will also have to add a SSS strength map to this, as some parts of the skin will be more affected by SSS than others.
5) Turn on the transslucency, and apply the same skin texture to the colour channel, but in this one, turn the base colour to a light grey tone. It helps keep the effect from getting oversaturated.
This will also require that you apply your SSS strength map to control which areas recieve the effect more than others.
Hope this helps
