To access the import and export settings into the Editor, select the Terrain component in the Inspector A Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. The Unity Editor enables you to import and export RAW heightmap files for a Terrain. A RAW file uses a 16-bit grayscale format that is compatible with most image and landscape editors. It’s good practice to store heightmaps as RAW files. You can also use 3D modelling applications, such as Houdini and World Machine, to generate Terrain, then import your Terrain into Unity as a heightmap. This is useful when you want to use real world height data to replicate a landmark such as Mount Everest, or work on a heightmap image in an external editor like Photoshop. You can import and export heightmaps into the Unity Editor. Example heightmap Importing and exporting heightmaps Heightmaps are built into the Terrain, and the values stored in a heightmap define the height of each point or vertex on the Terrain. Each pixel stores the height difference perpendicular to the face that pixel represents. It represents this array using a grayscale heightmap A greyscale Texture that stores height data for an object.

Unity represents the height of each point on the Terrain The landscape in your scene. Terrain tools that affect height, such as Raise or Lower Terrain and Set Height, use a grayscale texture called a heightmap.
