Variables

	Name	Description
uint8: 1	bCompressLightmaps	Whether to compress lightmap textures.
uint8: 1	bGenerateAmbientOcclusionMaterialMask	Whether to generate textures storing the AO computed by Lightmass.
uint8: 1	bUseAmbientOcclusion	If true, AmbientOcclusion will be enabled.
uint8: 1	bVisualizeAmbientOcclusion	If true, override normal direct and indirect lighting with just the AO term.
uint8: 1	bVisualizeMaterialDiffuse	If true, override normal direct and indirect lighting with just the exported diffuse term.
float	DiffuseBoost	Scales the diffuse contribution of all materials in the scene.
float	DirectIlluminationOcclusionFraction	How much of the AO to apply to direct lighting.
float	EmissiveBoost	Scales the emissive contribution of all materials in the scene.
FColor	EnvironmentColor	Represents a constant color light surrounding the upper hemisphere of the level, like a sky.
float	EnvironmentIntensity	Scales EnvironmentColor to allow independent color and brightness controls.
float	FullyOccludedSamplesFraction	Fraction of samples taken that must be occluded in order to reach full occlusion.
float	IndirectIlluminationOcclusionFraction	How much of the AO to apply to indirect lighting.
float	IndirectLightingQuality	Warning: Setting this higher than 1 will greatly increase build times! Can be used to increase the GI solver sample counts in order to get higher quality for levels that need it.
float	IndirectLightingSmoothness	Smoothness factor to apply to indirect lighting.
float	MaxOcclusionDistance	Maximum distance for an object to cause occlusion on another object.
int32	NumIndirectLightingBounces	Number of light bounces to simulate for point / spot / directional lights, starting from the light source.
int32	NumSkyLightingBounces	Number of skylight and emissive bounces to simulate.
float	OcclusionExponent	Higher exponents increase contrast.
float	StaticLightingLevelScale	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).
TEnumAsByte< en...	VolumeLightingMethod	Technique to use for providing precomputed lighting at all positions inside the Lightmass Importance Volume
float	VolumeLightSamplePlacementScale	Scales the distances at which volume lighting samples are placed.
float	VolumetricLightmapDetailCellSize	Size of an Volumetric Lightmap voxel at the highest density (used around geometry), in world space units.
float	VolumetricLightmapMaximumBrickMemoryMb	Maximum amount of memory to spend on Volumetric Lightmap Brick data.
float	VolumetricLightmapSphericalHarmonicSmoothing	Controls how much smoothing should be done to Volumetric Lightmap samples during Spherical Harmonic de-ringing.
