This project is based on Jourdan Tuffan's Esbatuan Architecture. I made this in order to become more comfortable working with a trim workflow and trying to reduce the amount of hand-textured assets in a scene. I heavily relied on Silke Van Der Smissen's dissertation on material layers and highly recommend it for anyone who is curious about it. Huge thanks to Lucas Annunziata for his mentorship, patience and positivity.
