Functions

Public

Name Remarks Include Path Unreal Specifiers
Builds all the data from SourceData. Is called by Cache(). SparseVolumeTexture/SparseVolumeTexture.h  

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. SparseVolumeTexture/SparseVolumeTexture.h  

void DropBulkData()

 Removes the StreamableMipLevels bulk data if it was successfully cached to DDC. SparseVolumeTexture/SparseVolumeTexture.h  

bool HasBuildFromDDCError()

   SparseVolumeTexture/SparseVolumeTexture.h  

bool HasStreamingData()

 Returns true if there are streamable mip levels. SparseVolumeTexture/SparseVolumeTexture.h  

bool RebuildBulkDataFromCacheAsync ( const UObject* Owner,
bool& bFailed
)

 Fills StreamableMipLevels with data from DDC. Returns true when done. SparseVolumeTexture/SparseVolumeTexture.h  

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

 Called when serializing to/from DDC buffers and when serializing the owning USparseVolumeTextureFrame. SparseVolumeTexture/SparseVolumeTexture.h  

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. SparseVolumeTexture/SparseVolumeTexture.h  

void SetHasBuildFromDDCError ( bool bHasError
)

   SparseVolumeTexture/SparseVolumeTexture.h  

Static
