Variables

  Type Name Description
Public variable TArray< TStaticArray< uint8, 12 > > DDCChunkIds  
Public variable TArray< uint32 > DDCChunkMaxTileIndices  
Public variable FIoHash DDCKeyHash  
Public variable FHeader Header  
Public variable int32 NumMipLevels  
Public variable uint32 ResourceFlags  
Public variable FString ResourceName These are used for logging and retrieving StreamableMipLevels from DDC in FStreamingManager.
Public variable TArray< uint8 > RootData Data for the highest/"root" mip level.
Public variable FByteBulkData StreamableMipLevels Data for all streamable mip levels.
Public variable FTileStreamingMetaData StreamingMetaData Info about offsets into the tile data.
Public variable FPageTopology Topology  

Functions

  Type Name Description
Public function bool Builds all the data from SourceData. Is called by Cache().
Public function void

Cache ( USparseVolumeTextureFrame* Owner,
UE::Serialization::FEditorBulkData& SourceData,
bool bLocalCachingOnly
)

 Cache the built data to/from DDC. If bLocalCachingOnly is true, the read/write queries will only use the local DDC; otherwise the remote DDC will also be used.
Public function void Removes the StreamableMipLevels bulk data if it was successfully cached to DDC.
Public function Const bool  
Public function Const bool Returns true if there are streamable mip levels.
Public function bool

RebuildBulkDataFromCacheAsync ( const UObject* Owner,
bool& bFailed
)

 Fills StreamableMipLevels with data from DDC. Returns true when done.
Public function void

Serialize ( FArchive& Ar,
UObject* Owner,
bool bCooked
)

 Called when serializing to/from DDC buffers and when serializing the owning USparseVolumeTextureFrame.
Public function void

SetDefault ( EPixelFormat FormatA,
EPixelFormat FormatB,
const FVector4f& FallbackValueA,
const FVector4f& FallbackValueB
)

 Sets empty default data. This is used when caching/building is canceled but some form of valid data is needed.
Public function void

SetHasBuildFromDDCError ( bool bHasError
)
