With Ray-Traced Irradiance Fields Global illumination light leaking is a persistent problem for artists in the game industry. Fixing this issue typically requires tasks such as creating manual clipping geometry, moving individual probes, or changing lightmap parameterizations. These are time consuming, limit lighting and geometry iteration time, and only work for static geometry. The arrival…
