This section allows you to control and fine-tune various aspects of the irradiance map. This rollout is enabled only when the irradiance map is chosen as the Primary engine on the Global Illumination rollout.
You can also make use of the Irradiance Map Viewer, a standalone tool that allows you to navigate through the 3D version of a scene presenting the GI samples taken.
