Below you can see some images I contributed to. I’m responsible for the majority of environment related shaders - their functionality, performance, and look - as well as specialized shaders for effects like water, snow, ice, fog, clouds, skin, blood, cloth, rocks, terrain, etc. That said, everything you see is the work of a host of extremely talented people, from concept, environment, lighting, character, rigging, and vfx teams all the way to engineering.
