In the very early days of Scatter in Poser (about 3 years ago), BagginsBill (BB) has done some research comparing the Subsurface Skin (with embedded specularity) node and the Scatter node (with Blinn specularity as a side arm). He found the latter by far superior, and he performed extensive research on it later on. Quite respectable.

Most of all that has landed in EZSkin and EZMat, and details can be found in the various forum threads at Rendo and at RuntimeDNA, if you're willing to plough them through.

My personal note on all this is that Scatter is quite a closed subset of the Custom_Scatter node, and one can gain a lot by mastering that one in detail. But it's a pretty tedious one, BB himself never really got into it, and it took me a few weeks to get on top of it.

So the choice is yours. Either take the fast and easy, but somewhat limited lane using EZSkin and the solutions established in the forum threads, or take the tough route which holds unlimited possiblities - in the end.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
