I worked on this Chalet section together with Andrew Watkins. Lighting was done by Joey Lenz. My main responsibilities as an environment artist included initial blockout, asset building, terrain creation, set dressing, creating shaders and optimization. As a Last of Us fan myself I must admit that it was personally pretty hard working on this section of the game knowing the outcome.
Working at Naughty Dog is a very collaborative process with many people involved in various fields and I want to thanks all those people for doing an amazing job.
