Blending between two materials with a mask?

Dear Unity Community,

I am looking for a shader like the one in the “Viking Village” project.
I have no experience in programming so I was hoping someone could help me out.

The shader in the Viking Village project however is for a specular setup.

I was simply looking for a shader that containts the same information as the standard unity shader but with a mask to blend between two materials. (metallic setup)

To illustrate what I mean a screenshot of the shader in the Viking Village project. (this one has a specular setup)
