How to texture crowded building

I have made a crowded building with the addon. Now i have to texture those buildings. The problem i have select each building unwrap align and huh if it was few 5-10 it was ok. Its more then75 building is there any quick tip or addon available to wrap the texture on those buildings.

I don’t make large project like this but you could find it in this tutorial.

I’ve tried making large scenes like you’re doing. You will come to a barrier in memory if you plan to texture everything and have it actually look good. Either your textures will be too large and look blurry, or they will be too repetitive because you have to cover so much area with the same patterns again and again.
