I am using Photoshop CC to draw a skybox -that is, an image composed of six sub-images that seamlessly assemble into a cube, like this:
As soon as I started drawing, I noticed that it is very difficult to make the image seamlessly loop across the different faces of the skybox.
I would like to know if there is a way to simplify the process of drawing such an image.
What I'm currently doing is to put guides in a grid the size of my skybox, paint, and then manually rotate the different faces to various configurations, and fix the seams. It is a very complicated work, and I would like to believe there is a better way to do this.
For example, I would like to be able to take a face of my image, copy it, rotate it and place the copy in a different part of the image, and make it so drawing on one of the copies automatically updates the other copy. I don't know how to do this, or if it is even doable in Photoshop.
Are there any ways to streamline the creation of such drawings in Photoshop?
I don't believe there is any good way for you to do this in Photoshop as-is. I would highly suggest you look at Quixel DDO + 3DO. It integrates directly with Photoshop and would allow you to paint in 3D using Photoshop brushes. It's fairly overkill for what you need, but should help you out.
