In some ways, this arrangement is preferred as it offers a rule you can follow over and over.
Here the Fresnel_Blend is being allowed to manage two layers - the surface, and the subsurface.
The surface effect handles reflections and specular at the material-air boundary. This is our Outer_Color, and consists of the sum of Reflect and Blinn. (Reflect for objects, Blinn for lights. But remember this is an artificial distinction caused by history. In Lux this is one thing, not two. I wish Poser had a new node that dealt with both.)
The subsurface effect is our Inner_Color. In this case we use a traditional Diffuse, but in a moment you'll see how we change that.
A render of this would look identical to the shader I just gave you.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
