Light leaking is a persistent problem for artists in the game industry. Fixing this issue typically requires creating manual pre-probes or doing additional lightmap work, which is difficult and time consuming to do. WIth the arrival of ray tracing, a better solution has emerged. This video is an 8:00 minute excerpt from Morgan McGuire’s GDC 2019 talk, “Dynamic Diffuse Global Illumination With Ray Traced Irradiance Fields”. This is for an advanced engineering audience.
