It was a huge honour for me to be a part of Dneg's team on Dunkirk. As it was said, there's not much of an VFX in the film, however there were some nice assets to create (not all of them were used, sadly). I was responsible for texturing on this project and I was lucky enough to create textures and initial lookdev for sinking minesweeper, which was the biggest CG asset in the film, it was particularly challenging because of the insane IMAX resolution and high demand for texture detail. I also did textures for the Moonstone digi double and few other small flotilla ships.
