Terrain and Textures

Using the Terrain tool in Unity allows you to quickly create an environment, such as mountains etc, with a tool similiar to a paintbrush. You can basically 'draw' the mountains and sculpt them into the height/smoothness you want.

Texturing these elevation you create suddenly will give atmosphere to what you are creating. Layering and collecting different textures allows a level of detail to be achieved and adds to the overall effect of the environment. Adding texture is also done using a paintbrush like tool, this allows some control and 'artistic flare' to be added.

Terrain assets can also be downloaded, for example trees, this then allows you the option the 'paint' trees onto the terrain, which is incredibly useful for backgrounds.
