Naughty Dog’s Yibing Jiang has spilled some tantalizing tidbits on the shader work that goes into creating the stunning visuals seen in its hotly anticipated action-adventure sequel, Uncharted 4: A Thief’s End. As the game’s Shading Artist, Jiang is instrumental in creating Nathan Drake’s dashing next-generation looks, and shared some comments on how the studio was able to overhaul his chiselled features for PS4. "Real-time rendered in game. This is not CGI or pre-render, which means all the shading features for skin, hair, eyes need to be written in code. Using Disney Diffuse model, GGX Brdf model and Screen Space Subsurface. Hair is using Kajiya-kay Brdf model. Frank Tzeng did the sculpting and texturing for his face and arms." It’s not just Drake’s boyish good looks that have seen a considerable improvement for his PS4 debut. The cheeky fortune hunter’s clothing has also received just as much attention, which Jiang further explains: “Real-time rendered in game. This is not CGI or pre-render, built the fabric shader package for all the main characters and npc characters as well. Using Disney Diffuse Model, recreated Brdf model just for the fabric, also added special cheap Sub-surface Scatter. All the fabric details, stitches, small wrinkles, wear and tears were built in shader. Colin Thomas did modeling and texturing part for the outfit.” Uncharted 4 received its first gameplay video at the PlayStation Experience a few weeks ago. Naughty Dog soon begun drip-feeding us a number of facts about its upcoming sequel, including the fact Drake will support 800 facial animations and fully-animated gun straps. The developer also released a high-res comparison shot of Drake’s Uncharted 4 model alongside his Uncharted 3 counterpart. Uncharted 4 is due for release in 2015. Source: PSU
