I've been working on this floor tile texture for about two weeks, based on this concept art piece found on ArtStation (https://www.artstation.com/artwork/QGXxx) by James Ross McNab.
It had a really awesome pattern that I wanted to create a material for.
I'm also working on other textures based on this same concept piece, but so far this one is my favorite.
