Advanced Graphics Summit: Making Connections: Real-Time Path-Traced Light Transport in Game Engines
Path traced effects in games have been a dream of many since the early days of real-time rendering. The advent of hardware accelerated ray tracing and recent advances in algorithms derived from Reservoir-based Spatio-Temporal Importance Sampling (ReSTIR) have turned those dreams into reality. In this session, Evan and Adam discuss the theoretical and practical elements necessary to add real-time pathtraced lighting to an advanced, modern game engine (Unreal Engine 5). Specifically, the team discusses changes to the light transport model and scalability that enhance existing engine systems to handle dramatically more complex lighting environments.
