The landscape material creates not just a texture on the landscape it includes grass, shrubs, rocks etc…
It is not painted using the “foliage” mode.
The materials are part of the “MW Conifer Tree Forest Biome” asset pack in the marketplace.
You can see in the first image that the landscape in the distance has the texture but not the geometry of the bushes and rocks. When you move the camera closer the material shows the geometry(2nd image).
