Building a virtual diorama of Arizona in Unreal Engine: Part 1

This is part 1 of a video series where I create a virtual diorama of the beautiful state of Arizona with moving water, and eventually freeways, people, buildings, and animals, most of which can be procedurally generated using elevation data or height maps.

This is less of a tutorial and more of a journey through my trial and error of creating this.
This is not a video showing you THE way, this is a video showing you my way.

Part 2 Development Journal:
7/9 8:28 PM: Turns out this projects scale was 20x too small. I just scaled it properly and now need the partition manager just to continue development at a reasonable framerate.
