Using skyboxes in unity3d
I offer the readers of Habrakhabr a translation of the Unity - Using Skyboxes publication from the Unity company blog.
Additional materials for the article Skybox and Cubemap
Skybox is a panoramic texture that is behind all the objects in the scene to simulate the sky or a big city or any other perspective at a great distance (a kind of background). This lesson explains how to use skybox in Unity .

Skybox - a panoramic view divided into six textures, representing six visible directions along the main axes (up, down, left, right, forward and backward) (up, down, left, right, forward and backward) . If the Skybox is created correctly, the texture images will be as a unit along the edges to give a continuous surrounding image that can be viewed “from the inside” in any direction. The panorama is behind all other objects in the scene and rotates in accordance with the current orientation of the camera (not to be confused with the position of the camera, which is always taken to be in the center of the panorama). Skybox is thus a simple way to add realism to the scene with a minimum load on the video card.
Unity comes with a number of high-quality Skybox in the Standard Assets package (menu: Assets> Import Package> Skyboxes ), but you can also find suitable sets of panoramic images from online sources or create your own using 3D modeling software. Assuming you already have six image textures for the Skybox , you must import them into Unity . Then go to our skybox , then go to the Inspector panel. And set its properties, set the Wrap Mode property to the value of the Clamp (if you set the Repeat value, the edges of the images will not form a “seamless” texture).
Skybox itself is actually the type of material that one of the shaders uses in the RenderFX submenu. If you select the Skybox Shader , you will see in the inspector panel something like the following, with six examples of textures:
The Skybox Cubed shader works basically the same, but requires textures to be added to the cubemap asset (menu: Assets> Create> Cubemap ). Cubemap has six texture slots with the same values ​​as the Skybox in the material inspector panel.
After it is created, you can set the new Skybox as the default Skybox (for the entire project) in the visualization settings inspector (menu: Edit> Render Settings ). You can override the default Skybox for each camera by assigning a new Skybox in the Camera > Skybox component (visible in the camera inspector).
