Today I want to show you how to use a 360° panorama picture as a skybox for Unity. As you may know, skyboxes are usually created from 6 images (cubemaps), with each image representing one of the sides. However, 360° photos usually use a so-called "Equirectangular" format, which looks something like this:
So in order to be able to use such an image in Unity, the idea of creating a cubemap from a 360° photo is obvious. But there is an easier way, which I would like to show you now: Cubemap: I start with my image, which I import into Unity. Then I select it and change the Texture Shape property from 2D to Cube. I then save the changes by hitting Apply and then create a new material. I change the shader from default to Skybox - Cubemap and specify the image I want to use.
That's almost it, now you only have to set the Skybox via Window - Lighting Settings and already you have your image and can integrate it into your projects.
