At last building is up! Using just basic and quick 3d modeling techniques, I did two module of the panels and duplicate/instance it around. My standard process of 3d modeling is not to collapse any modifiers as much as possible for me to have more flexibility to quickly edit in one go or work backward when necessary. I also prepare two materials with different ID’s. Then, I use RandomObjectSelection script from 3dteamz.com a quick way to select objects by percentage and apply the materials randomly to give a natural look and subtle effect. A time saver.

Next step will be on ground works…That’s it for now of my work in progress. Cheers everyone…
