Variables

Public

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