HOW I MADE IT: PART 2D - ROCKET UVs

In this tutorial series, I walk you through how I made this image which was inspired by the amazing work of Matt Dixon. The original purpose of this image was merely to try some texturing options, but people liked it enough to ask if I could demonstrate how I made it. So here we go!
This will be a lengthy tutorial broken into individual segments, so feel free to check em out in order, skip the ones you don't care for, or just pick and choose. Whatever floats your boat.
I use a handful of add-ons for my work. You don't need these add-ons to create this image, but why inflict more pain? The add-ons I use are vital to my workflow and just make working in Blender more enjoyable, at least for me anyway. They are:
