well if you modeled the elements yourself and had more time you could model and bake from a high poly to a low poly workflow depending on how much time you have, exactly how you model for games, i use this all the time and some 200,000 poly models suddently are 5 or 6000 and even less, its a great way to work and then you can incorporate quixel and substance painter in the workflow and then no need to dirt maps etc, i know alot of arch viz people run away from it but if you have time for a project its the way to go
