The intensity of surface albedo throughout the Scene when considered in lighting calculations. This value influences the energy of light at each bounce. (Editor only).
When light bounces off a surface, it is multiplied by the albedo of the surface. Change this value to increase or decrease the intensity of albedo used throughout the Scene.
The range is 0 through 10. The default value is 1.
This setting affects lightmaps generated by the Baked Global Illumination system and the Enlighten Realtime Global Illumination system.
When Unity serializes this LightingSettings object as a Lighting Settings Asset, this property corresponds to the Albedo Boost property in the Lighting Settings Asset Inspector.
