Variables

  Type Name Description
Public variable TObjectPtr< class UAssetImportData > AssetImportData  
Public variable bool bAllowCPUAccess Whether to keep vector field data accessible to the CPU.
Public variable FVectorFieldResource * Resource The resource for this vector field.
Public variable int32 SizeX Size of the vector field volume.

)

  

Functions

  Type Name Description
Public function Const FVector

FilteredSample ( const FVector& SamplePosition,
const FVector& TilingAxes
)

  
Public function FRHITexture * Returns a reference to a 3D texture handle for the GPU data.
Public function Const bool  
Public function void Initialize resources.
Public function Const TConstArrayView< InternalFloatType >  
Public function Const FVector

Sample ( const FIntVector& SamplePosition
)

  
Public function void Sets the bAllowCPUAccess flag and calls UpdateCPUData().
Public function void

UpdateCPUData ( bool bDiscardData
)

 Takes a local copy of the source bulk data so that it is readable at runtime on the CPU.

Overridden from UVectorField

  Type Name Description
Public function Virtual void

InitInstance ( FVectorFieldInstance* Instance,
bool bPreviewInstance
)

 Initializes an instance for use with this vector field.

Overridden from UObject

  Type Name Description
Public function Virtual void Called before destroying the object.
Public function Virtual Const void Gathers a list of asset registry searchable tags which are name/value pairs with some type information This only needs to be implemented for asset objects
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 void

PostEditChangeProperty ( FPropertyChangedEvent& PropertyChangedEvent
)

 Called when a property on this object has been modified externally
Public function Virtual void Called after the C++ constructor and after the properties have been initialized, including those loaded from config.
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.
