New layered skin shader for make-up and presets.

I hope to exchange make-up more flexible.  There are many character skin preset, and make-up products already, but hope to re-use them with stable rule.

DS offer LIE, or shader property to layer, but there seems no clear rule, how vendor make base skin mat with make-up. then  vendor may include make up with diffuse, or top coat , etc. 

Usually I use LIE to overwrap make-up, or use Image editor, for each property, with alpha overalay, but I think, this can be easy achived by Iray shader, and divided new layer property for make-up .

the new skin shader structure is like that,,  

base = uber iray shader (most of vendror offer skin preset for daz uber iray shader,,) 

new layer with  each properties (diffuse, bump, specular (metalness etc), sss) etc.

then most of character skin already include base skin (without make-up) preset for base.

I hope , vendor offer preset which only change properties value (include texture with alpha) for new make-up layer.  (not only make-up,, it can be use for dirt, etc)

Even though vendor wolud not like to offer new preset for new shader, if there is new skin shader which can keep compatiblity with daz iray uber shader, we can easy add new make-up texture with alpha, and set value, then overwrap many skin product. (or we need cut out opacity property in new make-up layer to use jpeg)  and can make make-up preest which change "make-up" layer only.

And detail make-up vendor can offer more products for each parts,  which can easy use with other character base mats which user already bought for daz iray uber shader.
