Problem using Open world demo material


I’ve got a maze type map thats basically a hilly landscape with a path that runs through it.

I want this environment to look like the open world demo, with green grassy hills and a stony pathway.

I’ve used these two tutorials for both grass and foliage:

The end results so far are nothing like “open world” I thought this would be a relatively easy process in that I’d only need to copy the material across and paint the relevant layers on.

Can someone please help?
