How can I make a simple hardsurface shader that works like marmoset toolbag 2?

Why should I leave specular at 0? The whole point of the specular map is to control the reflectivity and reflected color of different parts of my object. I have 5 different materials In this mesh that marmoset was able to show through texture and not actual different shaders. For example I have plastic, rubber, paper, painted metal, and a chrome like metal that I want to be able to store all on one shader(glass was a different shader) that illustrates the principles from marmosets pbr workflow. It almost seems to me like UE4 forces you to do something similar to a metalness workflow but not all artists want to work that way I still like my specular maps. I guess I will have to read up on the material editor and try to find a way to get the same results I can get in marmoset. I was hoping it would be a bit simpler than that. I’m going to go through the example projects and see if they have a shader that does what I want first though.

Are you talking about RGB Mask packing? If so you can do it inside of UE4 but it’s not as simple as Marmoset makes it. You need to build that shader using either the make or break material attribute nodes or buy making a bunch of different material functions that you can blend together using the material Layer Blend nodes.
