Photoshop Hard Light blend mode in UE4 shader?

Hello everybody,

I am trying to figure out how can I create a shader in Unreal 4 where I can add a texture which would be blended on top of the Albedo with the same effect as Photoshop Hard Light. This is just intended to get some texture variation on tileable textures.

This is my asset, (in substance painter)




this is the Detail map I painted


and this is the Detail map with Hard light effect




so



By doing this I am getting some texture variation. The big question is

Can anyone please share some wisdom and help me figure out how to do this in UE4?

I am an UE noob, but I think this is not a very hard thing to achieve.

Any help will be very appreciated,

Thank you beforehand!!
