Size of an Volumetric Lightmap high detail loading cell.
◆ bCompressLightmaps
| uint8 FLightmassWorldInfoSettings::bCompressLightmaps |
Whether to compress lightmap textures. Disabling lightmap texture compression will reduce artifacts but increase memory and disk size by 4x. Use caution when disabling this.
◆ bGenerateAmbientOcclusionMaterialMask
| uint8 FLightmassWorldInfoSettings::bGenerateAmbientOcclusionMaterialMask |
Whether to generate textures storing the AO computed by Lightmass. These can be accessed through the PrecomputedAOMask material node, Which is useful for blending between material layers on environment assets. Be sure to set DirectIlluminationOcclusionFraction and IndirectIlluminationOcclusionFraction to 0 if you only want the PrecomputedAOMask!
◆ bUseAmbientOcclusion
| uint8 FLightmassWorldInfoSettings::bUseAmbientOcclusion |
If true, AmbientOcclusion will be enabled.
◆ bVisualizeAmbientOcclusion
| uint8 FLightmassWorldInfoSettings::bVisualizeAmbientOcclusion |
If true, override normal direct and indirect lighting with just the AO term.
◆ bVisualizeMaterialDiffuse
| uint8 FLightmassWorldInfoSettings::bVisualizeMaterialDiffuse |
If true, override normal direct and indirect lighting with just the exported diffuse term.
◆ bWorldPartition
| bool FLightmassWorldInfoSettings::bWorldPartition |
◆ DiffuseBoost
| float FLightmassWorldInfoSettings::DiffuseBoost |
Scales the diffuse contribution of all materials in the scene.
◆ DirectIlluminationOcclusionFraction
| float FLightmassWorldInfoSettings::DirectIlluminationOcclusionFraction |
How much of the AO to apply to direct lighting.
◆ EmissiveBoost
| float FLightmassWorldInfoSettings::EmissiveBoost |
Scales the emissive contribution of all materials in the scene. Currently disabled and should be removed with mesh area lights.
◆ EnvironmentColor
| FColor FLightmassWorldInfoSettings::EnvironmentColor |
Represents a constant color light surrounding the upper hemisphere of the level, like a sky. This light source currently does not get bounced as indirect lighting and causes reflection capture brightness to be incorrect. Prefer using a Static Skylight instead.
◆ EnvironmentIntensity
| float FLightmassWorldInfoSettings::EnvironmentIntensity |
Scales EnvironmentColor to allow independent color and brightness controls.
◆ FullyOccludedSamplesFraction
| float FLightmassWorldInfoSettings::FullyOccludedSamplesFraction |
Fraction of samples taken that must be occluded in order to reach full occlusion.
◆ IndirectIlluminationOcclusionFraction
| float FLightmassWorldInfoSettings::IndirectIlluminationOcclusionFraction |
How much of the AO to apply to indirect lighting.
◆ IndirectLightingQuality
| float FLightmassWorldInfoSettings::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. It can be useful to reduce IndirectLightingSmoothness somewhat (~.75) when increasing quality to get defined indirect shadows. Note that this can't affect compression artifacts, UV seams or other texture based artifacts.
◆ IndirectLightingSmoothness
| float FLightmassWorldInfoSettings::IndirectLightingSmoothness |
Smoothness factor to apply to indirect lighting. This is useful in some lighting conditions when Lightmass cannot resolve accurate indirect lighting. 1 is default smoothness tweaked for a variety of lighting situations. Higher values like 3 smooth out the indirect lighting more, but at the cost of indirect shadows losing detail.
◆ MaxOcclusionDistance
| float FLightmassWorldInfoSettings::MaxOcclusionDistance |
Maximum distance for an object to cause occlusion on another object.
◆ NumIndirectLightingBounces
| int32 FLightmassWorldInfoSettings::NumIndirectLightingBounces |
Number of light bounces to simulate for point / spot / directional lights, starting from the light source. 0 is direct lighting only, 1 is one bounce, etc. Bounce 1 takes the most time to calculate and contributes the most to visual quality, followed by bounce 2. Successive bounces don't really affect build times, but have a much lower visual impact, unless the material diffuse colors are close to 1.
◆ NumSkyLightingBounces
| int32 FLightmassWorldInfoSettings::NumSkyLightingBounces |
Number of skylight and emissive bounces to simulate.
Lightmass uses a non-distributable radiosity method for skylight bounces whose cost is proportional to the number of bounces.
◆ OcclusionExponent
| float FLightmassWorldInfoSettings::OcclusionExponent |
Higher exponents increase contrast.
◆ StaticLightingLevelScale
| float FLightmassWorldInfoSettings::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). 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.
◆ VolumeLightingMethod
Technique to use for providing precomputed lighting at all positions inside the Lightmass Importance Volume
◆ VolumeLightSamplePlacementScale
| float FLightmassWorldInfoSettings::VolumeLightSamplePlacementScale |
Scales the distances at which volume lighting samples are placed. Volume lighting samples are computed by Lightmass and are used for GI on movable components. Using larger scales results in less sample memory usage and reduces Indirect Lighting Cache update times, but less accurate transitions between lighting areas.
◆ VolumetricLightmapDetailCellSize
| float FLightmassWorldInfoSettings::VolumetricLightmapDetailCellSize |
Size of an Volumetric Lightmap voxel at the highest density (used around geometry), in world space units. This setting has a large impact on build times and memory, use with caution.
Halving the DetailCellSize can increase memory by up to a factor of 8x.
◆ VolumetricLightmapSphericalHarmonicSmoothing
| float FLightmassWorldInfoSettings::VolumetricLightmapSphericalHarmonicSmoothing |
Controls how much smoothing should be done to Volumetric Lightmap samples during Spherical Harmonic de-ringing.
Whenever highly directional lighting is stored in a Spherical Harmonic, a ringing artifact occurs which manifests as unexpected black areas on the opposite side. Smoothing can reduce this artifact. Smoothing is only applied when the ringing artifact is present. 0 = no smoothing, 1 = strong smooth (little directionality in lighting).
