public bool extractAO ;


Whether the Progressive Lightmapper extracts Ambient Occlusion to a separate lightmap. (Editor only).

When this is set to true, Unity saves the filtered Ambient Occlusion (AO) texture to disk as a separate lightmap, in addition to applying it to the regular lightmaps. When this is set to false, Unity does not save the filtered AO texture to disk separately.

Use this if you need to access the AO data separately.

Note that the values from _aoExponentDirect and _aoExponentIndirect are not applied; instead, the default values are used. The resulting lightmap is saved to disk in the same location as the other lightmaps.

This only works when autoGenerate is set to false, and ao is set to true.
