Take a look at the Death Star construction timelapse.
“This is a personal project that I worked on with my brother. I enjoyed watching a little bit of Death Star assembly in Rogue One, but I wanted to see more. I came up with a very simple method of revealing geometry with Lightwave’s instancing tool, and then started building the underlying parts of the fully armed and operational battlestation. Since there was a lot of procedural animation, I was seeing a lot of interesting shapes appear that I hadn’t planned, but the thing that really pulls it together is the new score by Ben Botkin.”
