Rolling Hills is part of the StampIT! Collection, a set of high-resolution 4K heightmap stamps and brushes. These heightmap textures can be used as brushes with Unity terrain tools to paint features on your Unity terrain. The asset includes 30 high-quality textures and brush presets, but does not include terrain textures.
Stamping is a process that blends textures together, supported by Unity out of the box. The Unity terrain tools provide a convenient means to blend images together, with a brush preview that allows you to adjust the stamp in detail before applying it. For an even better experience, consider installing the free Unity Terrain Tools package, which extends the terrain tools palette with additional tools.
If you need complete terrains imported into Unity, including textures, consider using World Creator, a highly recommended application.
For more information about the brushes, visit the official Unity documentation on Brushes and Stamping. The Unity terrain tools and World Creator can be used in conjunction with this asset to create stunning 4K heightmaps.
