Specifies the maximum number of bounces that the Progressive Lightmapper computes for each light ray. (Editor only).
A higher number of bounces results in more realistic lighting, but results in longer bake times.
The range is 0 to 4. The default value is 2.
This setting affects lightmaps generated by the Baked Global Illumination system. It applies only when using Progressive Lightmapper.
When Unity serializes this LightingSettings object as a Lighting Settings Asset, this property corresponds to the Bounces property in the Lighting Settings Asset Inspector.
