Landscape material height help

I’m extremely new to materials. In fact, i barely know anything about materials.
If someone could also help me sharing some articles or book about it i’d apreciate, but my problem here is this:
I’m trying to create a Landscape material, this material use world displacement on some of the blends.
The textures for the material i’m using come from Kite demo, it’s the T_gravelTile_01 textures.
But i’m not sure how to set this up on a landscape material to get the feel that the rocks are coming out of the ground from this print from UE4 Landscape grass material guide: https://docs.unrealengine.com/latest/images/Engine/OpenWorldTools/ProceduralFoliage/QuickStart/6/T_On_Your_Own.jpg

I could get this effect with a regular material.
Here’s how i did it with a regular material and how it looks :

But when i try to do it with a landscape material it looks really weird, but since i don’t know much i don’t know where i’m doing wrong.
Here’s how i did the LS mat and how it looks:
PS: Both of them have the same tesselation setup.

No need to follow it but at least have a look so that U have an idea how the things work .(since U are still learnng)

If U want to add a realism to rocks here is a vid…

Ue4: advanced materials (Ep.1 Using CrazyBump) - YouTube(this is Ur answer hope this is understandable)

One thing I need to apologize is I won’t be too active for a week as I am void of a good internet connection so it might happen that I am not that prompt in replying back to Ur queries.

Another thing U should also know how to create realistic textures and bump maps too using any good photoshop tool
if possible so that U get the best of results. (try the CrazyBump software works for me)
