Specifies the radius the Progressive Lightmapper used to filter the indirect lighting component of the lightmap when using Gaussian filter. (Editor only).
The range is 0 through 5. The default value is 5. A higher value increases the strength of the blur, reducing noise from indirect light in the lightmap.
This setting affects lightmaps generated by the Baked Global Illumination system. It applies only when using the Progressive Lightmapper.
When Unity serializes this
LightingSettings object as a Lighting Settings Asset, this property corresponds to the Filtering > Indirect Filter > Radius property in the Lighting Settings Asset Inspector.
