Variables

  Type Name Description
Public variable FVector Add Add factor for calculating UVs from position.
Public variable int32 AllocationTexelSize Size in texels of the allocation into the volume texture atlas.
Public variable bool bHasEverUpdatedSingleSample Whether SingleSamplePacked has ever been populated with valid results, used to initialize.
Public variable bool bIsDirty Whether the primitive allocation is dirty and should be updated regardless of having moved.
Public variable bool bPointSample Whether this allocation is a point sample and therefore was not put into the volume texture atlas.
Public variable bool bUnbuiltPreview  
Public variable float CurrentDirectionalShadowing Current shadowing of the stationary directional light.
Public variable FVector4f CurrentSkyBentNormal Current directional occlusion of the sky.
Public variable FVector MaxUV Used to clamp lookup UV to a valid range for pixels outside the object's bounding box.
Public variable FIntVector MinTexel Block index in the volume texture atlas, can represent unallocated.
Public variable FVector MinUV Used to clamp lookup UV to a valid range for pixels outside the object's bounding box.
Public variable FVector Scale Scale factor for calculating UVs from position.
Public variable FVector4f[3] SingleSamplePacked0 Current SH sample used when lighting the entire object with one sample.
Public variable FVector4f[3] SingleSamplePacked1  
Public variable FVector4f SingleSamplePacked2  
Public variable FVector SingleSamplePosition Current position of the single lighting sample. Used for interpolation over time.
Public variable float TargetDirectionalShadowing Target shadowing of the stationary directional light.
Public variable FVector TargetPosition Position at the new single lighting sample. Used for interpolation over time.
Public variable FVector4f[3] TargetSamplePacked0 SH sample at the new single lighting sample position. Used for interpolation over time.
Public variable FVector4f[3] TargetSamplePacked1  
Public variable FVector4f TargetSamplePacked2  
Public variable FVector4f TargetSkyBentNormal Target directional occlusion of the sky.
