I was privileged to be part of the concept design team at Weta Workshop for Men in Black: International. My main task was to help our concept artists visualize the guns and props in 3D, I got to design some of them too which is very cool. And also, some of the 3d models we did went straight to manufacture which they used on set (with few modifications). :)
3d models were done using Zbrush and Maya, rendered in Marmoset and enhanced in Photoshop. :)
