Description

Specifies the threshold the Progressive Lightmapper uses to filter the indirect lighting component of the lightmap when using the A-Trous filter. (Editor only).

The range is 0 through 2. The default value is 2. A higher value increases the threshold, reducing noise in the indirect layer of the lightmap. Too high of a value can cause a loss of detail 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 > Sigma property in the Lighting Settings Asset Inspector.
