Hi, thanks for the answer, i tried that layer mix but i don't see anything inside the render maybe i did something wrong
I can't tell what you're doing wrong, but a similar network is working for me. You forgot to use a mask of some kind, but that should be okay as it will mix using a constant value.

Is it a basic feature though? It's not even important or necessary the vast majority of the time. What defines material complexity is number of bsdfs, and the standard surface has plenty of those. Layering effects can be done on the input side and get almost the same result as layering on the bsdf side. I know some artists like to treat everything like layers, but it's a lot less efficient to build a shader that way.

It depends on your authoring strategy. Some companies (like ours) prefer to carry large templates of layered materials, which is done for long-term durability and maintenance convenience, along with a strong hint of legacy. Sure, there are other ways to do it, sometimes with the goal of being more efficient for the renderer, or for rapid authoring using tools like Substance/etc for example. The latter approach is probably more common in modern or smaller-scale pipelines - which is just a guess of mine, really. Either way, I expect SideFX might address layer mixing in short shrift if you make your voice heard... which you now have
