One of the benefits of the Height Map Terrain is that it combines with the LOD (Level of Detail) feature, which presents you a large terrain with exquisite details, materials and textures without increasing the burdens of your computer to render the remote surface details that are difficult for human eyes to notice. It is suitable for faster editing and previewing. If you want to see the fine render results, then turn the LOD off.
