説明

Specifies the threshold the Progressive Lightmapper uses to filter direct light stored in the lightmap when using A-Trous filter. The default value is 0.5. The value range is 0 to 2.

A higher value will increase the threshold, reducing noise in the direct layer of the lightmap. Too high of a value can cause a loss of detail in the lightmap.
