Modular building kit for a personel project. It took me quiet some time to finish it. Each terrace mega structure is build up from vertical column and corner parts. The parts themselves are pretty basic. Build up from straight shapes and combined with my own greebles. I've used also some parts from the greeble kit from Andrew Averkin (https://www.artstation.com/artwork/6ggB0) which was extremely helpful to make all the tiny details in reasonable time.
All elements are geometry with UV-mapping or procedural materials. The greebles were done in 3DS Max. I switched to Blender (with Version 2.8 :) and created the final layout there. The final render was done in Vue (app. 12.5 billion polys in a 7.5 GB Vue-file).
