The thing is that the guide I'm following uses 3Dcoat to have the texture projected from the one side to the other side. I figured that Blender would be able to do this also, but I'm not quite sure how it works. I've tried to search the internet and there's probably guide, but I do really not know what to search for to find what I'm looking for.

Thanks for the help, I found what I was looking for. https://www.youtube.com/watch?v=hb-OZTNFatw
