Procedural (kinda) house created on substance designer. There are a few variables that can be modified without causing significant issues, including wall Z and X lenght, number of floors, gap between windows, window, door, detail and roof meshes and a few more things. The graph itself is quite messy.
At some point I gave up trying to add more features since the graph was quite messy. As my first real project on a model graph I'll call it a success.
