A 100 slot multi sub object material!!! That must take an age to set up and again to load each time you open the file. How does the script differentiate between roof and wall, is it down to direction of normals and face orientation? (edit: sorry, just read the answer to that in the earlier posts, I promise to pay more attention in future)
Looks amazing, water towers and masts will look great if you do that too. Will we also get to see clouds and a helicopter buzzing past below?
