I am attempting to create a skycraper using array mesh. I intend to start off with the window element and then create each wall of the floor using this element. It will be similar to the arrayBuilding.zpr file that comes with zBrush 4R8. The problem is that I cannot get past the first transform stage to create the second wall. I am looking for tutorials to make such a building with four walls at right angles. Does anyone have any suggestions?
