Add Terrain and Skybox – Unity3D
You can add terrain in Hierarchy window by clicking on Create button.
But first, add a “directional light” in your scene to see your 3D objects clearly in your game scene. Click on terrain and its specifications appear on Inspector. There are 7 buttons at top for editing the terrain. You can create mountains, trees etc. by using this tool. Import a texture in your “Assets” file. Click edit textures in terrain window and select a texture to add your custom texture on terrain. Now, create mountains with first button at top. Use brushes in your scene window to create mountains.
If you want to add a skybox, select Main camera, Add Component>Rendering>Skybox. If you don’t have your custom skybox, import standard skybox package of Unity.
