I followed the one on unreal’s website, but once it got to the editing the material I was lost, I couldn’t find what was up on the tutorial and I couldn’t understand it as it either.
Are there any tutorials that explain that process more clearly?
Take a look at those tutorials

Thanks for that.
I have used world machine in the past, but it seems to be the way to go as far as setting up the general landscape is concerned, I guess I’ll still need to learn how to do texturing properly in UE4 though.
Another question, are there any tutorials to help you make a map like say the GTA ones (Only on a smaller scale of course)?
As far as I know there are no such tutorials around, but actually it will be just a world machine tutorial in combination with a world composition (level streaming) -> ?v=zxSBxJL5MkY
But you could take a look at some time laps videos to get an idea how to build a map. This channel has some very good ones: https://www.youtube/user/
