Hey guys, hopefully this will help a bit more!
I’ve attached a .zip which contains some UE4 UAssets and a UE3 UPK which has the materials + textures that I’m using, if you connect the nodes in the UE4 material in the same way as the UE3 one, or if you switch on live node preview, you’ll see that the nodes are doing some different things.
I’m fairly sure that the UE3 build I used for this package was Either March or Feb 2013 
Hope this helps!
You’ll notice that the tiling of the material goes a bit funky when the nodes are connected up in UE4 the same way, at the moment I’ve just omitted those extra steps.
