Whilst this project is a bit of a work in progress, I felt it's worth putting in an entry to show how far it's gotten.
Heavily inspired by the likes of Final Fantasy VII, its Mako Reactors, and many other environments both real or fictional that display a well-used industrial setting. I wanted to capture the aesthetic of the PS1 era with rendered backgrounds, yet push the boundaries and capabilities of my current knowledge, especially with materials.
I got a whole lot of material inspiration from the ace work of Sam Delfanti: https://www.artstation.com/artwork/ZGawv1
Also to say a big thank you to the epic folks over at The Base Mesh for all their advice and encouragement.
