Back in 2020 I had the pleasure to work on the NOMAD design with Gareth Edwards and James Clyne. Was a lot of back and forth since it was the main prop for the film.
The scale of the design was around 50miles wide, and so i tried to think about how people could move through it in a reasonable amount of time, how we could leverage the massive scale of the design.
The weapons area from below I wanted to feel like a beak with a bird's eye (if you see an under shot)
Everything was modeled in 3ds max. Unfortunately I didn't have time to do any super awesome renders, but that's what the movie is for.
