I had the opportunity to kickstart the early versions of Rakka's alien creature, Klum. Eventually, it was passed to our character artist Ian Spriggs who did majority of the designs and iterations. Simultaneously, Neill and I came up with the visuals and functions for their alien technology. Internally known as Swax, short for Swang Wax, these black matters can take any shape or density to meet different needs. Our effects artist Alex Lombardi then took it to what you see in the final film.
I was tasked to design both the interior and exterior looks to the alien structures. In some cases, I assisted in the matte painting of the final shot. Just like the Klum, the architectures are basically covered in Swax, built for the sole purpose of changing the earth's atmosphere into methane.
When we were building the universe of Rakka, we had to come up with multiple ways in which they can commute by. Although the final film briefly showcased two ship designs, we also had trucks, tanks, mechs and drones in the line up.
