Group nodes are an effective way to save time, that’s why I designed this pack, it contains twenty-four procedural shaders that will allow you to quickly apply your textures without going through UV unfolding. You can add “texture images” in some cases to give your personal touch.

So after using it, i love the idea, it’s almost a procedural shaders with dust and dirt sliders.
It remembers me a bit shaders of 3Dcoat PBR
but not enough realistic unfortunately and it doesn’t works on different scale and other scene,
I don’t know why.
I think if you work more on this shaders you will help the community.
Thank you, for your Opinion as soon as possible I will try to improve the content of this pack
