How to add height displacement to materials?

Many people have asked this question and no one seems to be getting an answer so I’m asking again to see if anyone knows. When you get a material on textures.com it comes with a height map. Without it, the material is dead flat. There’s no option for "World Displacement"like in UE5 so how do we add the height to the material?

Or are we stuck with flat looking surfaces in UEFN?

when you create a material, put your texture height map in the normal map slot.

There’s already a normal texture that comes with it, and if I were to put the height map in the normal slot it would replace it. I did it though, still didn’t change the height.

You can use the modeling mode’s displacement tool to add geometry based on the material/texture. Normally that would seem like a bad idea but with nanite it’s actually totally fine. (within reason of course!)

is there documentation or a tutorial on how to do this with nanite?

Actually life just got a lot easier if you are on 5.3, you can add the displacement from a texture. Unreal sensei has a good example here:
