How to Create a Skybox
In this tutorial we will learn how to create our own hand painted skyboxes for use in game engines like Unity. I will specifically demonstrate creating the assets needed for creating the 3d model for the skybox in 3ds Max, importing the into Mudbox and digitally painting the sky, and editing the 6 panel images needed for generating a cubemap or skybox in Unity. This method can also be useful for creating skyboxes for use in animation.
**Editor note**
At the end of this video I get seams showing in the skybox in Unity 5. I want to say I discovered what the issue is. In the texture import settings in Unity, you must select the textures and set their "Wrap Mode" to "Clamp". This solves the seam issues.
