Skyboxes are a great way to quickly fill up your game or movie scene although it can be tricky to wrap your head around if you don’t know how to make one. It can be difficult to find a decent skybox tutorial specifically for Unity3D using Photoshop. With the assistance of a tool called Pano2VR, it has become rather easy to create a skybox from scratch and quickly iterate on it until it fits your needs. By no means do I claim this method to be the best or fastest. However, it’s an approach that can help you out if you are in a pinch.
