What it does
LGI simulates global illumination. Global illumination is the way that light bounces around in the real world. LGI can add realistic diffuse lighting to scenes.
How it works
Local Global Illumination (LGI) uses a reflection probe to constantly re-render the local scene area. This means that LGI creates a map of the light in the area around the camera.
LGI then uses lighting algorithms to convert that map into a diffuse irradiance map. A diffuse irradiance map is a map that shows how much light is coming from different directions.
Finally, LGI uses post-processing to apply that diffuse irradiance map to the scene. This means that LGI adds the light from the diffuse irradiance map to the scene using lighting algorithms.
