Blender 2.79 Principled BSDF Shader + Substance Painter

[psychoboy852]

I want to have shiny paint on top of the metal material. I made a material in Substance Painter. If I use shaders from Andrew Price, I am able to achieve this effect. However if I try this with Principled shader, that shininess of the paint is gone. Maybe I’m doing something wrong?
Advice would be much appreciated, thank you.

Found a solution. The reason why it turned out this way is because I forgot to turn off “metal” channel in Substance Painter. Once I did the texture behaved as it should.
