Functions

  Type Name Description
Public function void

Cache ( bool bSkipDDCAndSetResourcesToDefault
)

 Caches the derived data (FResources) of this frame to/from DDC and ensures that FTextureRenderResources exists.
Public function bool Creates TextureRenderResources if they don't already exist. Returns false if they already existed.
Public function Static USparseVolumeTextureFrame *

GetFrameAndIssueStreamingRequest ( USparseVolumeTexture* SparseVolumeTexture,
float FrameIndex,
int32 MipLevel,
bool bBlocking
)

 Retrieves a frame from the given SparseVolumeTexture and also issues a streaming request for it.
Public function Const int32  
Public function UE::SVT::FResources *  
Public function bool

Overridden from UObject

  Type Name Description
Public function Virtual void Starts caching of platform specific data for the target platform Called when cooking before serialization so that object can prepare platform specific data Not called during normal loading of objects
Public function Virtual void Called before destroying the object.
Public function Virtual void Clear all cached cooked platform data
Public function Virtual void Clears cached cooked platform data for specific platform
Public function Virtual void Called to finish destroying the object.
Public function Virtual void

GetResourceSizeEx ( FResourceSizeEx& CumulativeResourceSize
)

 Get the size of the object/resource for use in memory tools or to display to artists/LDs in the Editor This is the extended version which separates up the used memory into different memory regions (the actual definition of which may be platform specific).
Public function Virtual bool Have we finished loading all the cooked platform data for the target platforms requested in BeginCacheForCookedPlatformData
Public function Virtual void Do any object-specific cleanup required immediately after loading an object.
Public function Virtual void Handles reading, writing, and reference collecting using FArchive.
Public function Virtual void All caching has finished for this object (all IsCachedCookedPlatformDataLoaded functions have finished for all platforms)
