Several exclusion rectangles/polygons have been created in FS20 to remove orb lights, roads, etc. These function just fine in FS20. However, these do not seem to function when the scenery is sideloaded into FS24: despite all the exclusions, the orb street lights remain to be visible near the runways.
I have not tried converting the scenery into FS24 natively, however, we’d like to avoid this given the increased maintenance complexity.
