How to render a skybox in a cube?


I am new to here. I have some my own created beach background images and i want to use them as skybox. I want to render my 6 images(6 parts of my 360 degree scenery) into a cube. Please give me some reference, but in detail.

Hello, you can invert a cube mesh on a Blender(if you want i can show it to you), and then you can assign to it a uv map, then assign the skybox shader.
