fktifzobr@mail.ru, I'm glad it worked out. Now that everything is working and the process is streamlined, I can offer my help. I'm not very good at modeling, but I can cut off someone's legs (or other body parts). If you need anything, feel free to ask.
By the way, it would be good to edit the buildings; a simple retexture isn't enough.
And there's also a mod for unique buildings for creatures of the fourth, fifth, sixth, and seventh levels; with it, you can turn a human city into a black tower with dwarven buildings.
