This project was a 3D lighting study at first, based on Alexander "Minze" Thümler's Temple Interior (https://www.artstation.com/artwork/rl6K6).
See the Lighting Study pictures.
I also learned Substance Designer recently, and decided to give it a go : doing the whole game-ready 3D environment. I worked with Blender for the modelisation, Substance Designer for the textures, and Unreal Engine for the lighting and rendering.
Adapting Minze's work into a 3D scene was really thrilling and a great technical exercice. I've focused on lighting, composition and materials, and therefore used UE4 megascans for the plants (Megascans - Lush Plants).
