Window Randomzier for City Rendering

Hey all,

I didn’t know for what to search, that’s why I ask. Is there a tool for automatically generate facade/ window patterns for surrounding buildings of a hypothetical site to do a nice day or night perspective rendering?

I thought of doing a grasshopper script that divides surrounding buildings, generated by elk and osm data in different levels hight, sometimes give it balconies and randomize the window sizes and structures. Did anyone did this already or is the a different tool?

Thanks in advance guys!
