thanks, actually the whole shot including the animation so far was only 5 days of work. There are no instances but lots of duplication. The city has lots of cubes rotated at different angles for the lowest buildings. the main city shapes are mostly 3-4 different groups of similar models rotated with a few hero buildings that should help everything not feel like exact copies. I hope. I ended up making hero models of the towers in zbrush and used very primitive shapes with no beveling. I made groups of those, then copied the groups and moved them around
