Albedo maps in unreal engine for

I created a metallic floor with a few bumpy parts. I am using Quixel Suite 2 and I created a great look for my metallic floor. I then exported from Quixel Suite 2 into a folder so I could bring everything into Unreal Engine 4:)
I imported my floor into Unreal Engine 4 and drag and dropped all four materials Quixel Suite 2 generated. I have my metallic, normal, another map I can’t remember right now and albedo. I was able to attach all materials to their slots but where do I place albedo? To get the best results what material slot can I drag Albedo map into to make things look great?

Did you ever get this figured out?
