When you manually adjust a city, do you place rows of buildings so that they follow the texture(s) or the actual street layout?
It was possible at Poland map, where there were five cities so done, taking 14 slots occupied by cities in load_ini file.
At Yugoslavia map, where much higher number of cities is present, it is not possible because of limited number of load_ini slots. Here only main landmarks in Yugoslavia cities, like fortresses, churches, mosques, universities, museums, railway stations, bridges and so on, are placed at proper places.
The landmark buildings are only placeholders mainly, because the creation of the new objects needed is out of my skillness so far. Only three churches in Beograd and Old bridge in Mostar are completely new objects , made by Molva from Aviaskins.
By using actual street layout , there is another Scylla and Charybda: the highways and railways inside the towns might be either as actual layout (then they will not be good for Il-2 vehicles traffic), or will be ugly shaped using Il-2 game defaults (but usable with Il-2 vehicles).
