UNreal Engine 4 How can I create Gloss Spec Material ?

Peksio

Hello, I am texturing asset in Specular Glossines workflow and I wanted to render it in UE4. But I don't know how to create material that will accept spec and gloss and won't need roughness. Is it even possible ?

I tried to use various functions like multiply, and x-1 but it is not working well for me  

Can someone please help me?

No. Not possible. Unreal expects metallic/roughness. Glossiness is just inverted roughness so that can work, but it can't utilize a specular map in the way that you want to use it.
