How to texture crowded building I have made a crowd of buildings with the addon. Now I have to texture those buildings. The problem I have is to select each building, unwrap it and align the texture - huh, if it was a few 5-10 it would be ok. But it's more then 75 buildings! Is there any quick tip or addon available to wrap the texture on those buildings?
It depends on how detailed you want your textures.
Here are a few non accurate and fast methods:

Copy the material

You can try to determine 4-8 types of buildings (skyscrapers, living houses, hospitals, schools etc), make textures for them and just copy-pasted a resulting material to the other buildings, depending on their types.

Select all meshes, the last one set up with a random texture of a skyscraper.
Then go to materials tab in properties, then copy the texture to other selected meshes.
After that, for each mesh: tab to enter edit mode, then U -> Smart UV Project.



One big mesh

You can connect all meshes into one (A to select, Ctrl+J to join them), tab, then U -> Smart UV Project and make one big texture for them. After that, you can tune them after unwrapping to get better result (e.g. scale properly; set up roofs if you have them in your texture, etc). After that, you can separate meshes. In edit mode P -> by loose parts. And you will get several buildings with the same texture.
