This talk focuses on R&D that has been conducted on Frostbite’s high quality static global illumination (GI) baking solution (Flux) to reach the goal of an interactive GI preview workflow for artists. It describes the techniques that were applied to migrate Frostbite’s lightmap and irradiance volume renderer to GPU using Microsoft DirectX Raytracing (DXR) first on NVIDIA RTX technology. Flux has been used in Star Wars Battlefront II, FIFA 18 and Madden 18.
Our friends at SEED have also been experimenting with raytracing & DXR. Check out PICA PICA.
