Lewis;
I found a tutorial for the creation of Skybox images for the Unreal Engine and started to follow the instructions.
A programme called "Spacescape" by Alex Peterson is a recommended app to use for the creation of a Skybox image. After creating the Skybox you would save the image and it would export around 6 images that would have to be sewn together in Photoshop. In order to do that the Nvidia texture tools had to be downloaded. I attempted to open the Spacescape software but it didn't seem to work. It may be a possibility I'll have to wait for an updated version.
