UPROPERTY (BlueprintReadWrite, EditAnywhere, Category=LightmassGeneral, AdvancedDisplay,
Meta=(UIMin="1.0", UIMax="4.0"))
float StaticLightingLevelScale
Remarks
Warning: Setting this to less than 1 will greatly increase build times! Scale of the level relative to real world scale (1 Unreal Unit = 1 cm). All scale-dependent Lightmass setting defaults have been tweaked to work well with real world scale, Any levels with a different scale should use this scale to compensate. For large levels it can drastically reduce build times to set this to 2 or 4.
