In this video I show how I create endless terrains with the FREE MapMagic2. I've sped up the video by around 3x and explained what's going on. It's more about the process than the detail since detail changes for each terrain. But you can always pause/slow the vid if you want to see the detail.
In this video I only use the free version of MapMagic2, but the intro and outro include some paid assets that I'll introduce in subsequent videos.
