Functions

  Type Name Description
Public function bool Convert input UTexture2D to single-channel.
Public function bool

UE::AssetUtils::ForceVirtualTexturePrefetch ( FImageDimensions ScreenSpaceDimensions,
bool bWaitForPrefetchToComplete
)

 Issue requests to the render thread to force virtual textures to load for the given screen dimensions.
Public function FName

UE::AssetUtils::GenerateNewMaterialSlotName ( const TArray< FStaticMaterial >& ExistingMaterials,
UMaterialInterface* SlotMaterial,
int32 NewSlotIndex
)

 Generate a new unique material slot name for the given SlotMaterial and NewSlotIndex, ensuring that the name is not already used in the set of ExistingMaterials
Public function bool

UE::AssetUtils::GetStaticMeshLODAssetMaterials ( UStaticMesh* StaticMeshAsset,
int32 LODIndex,
FStaticMeshLODMaterialSetInfo& MaterialInfoOut
)

 Extract information about the material set for a given LODIndex of a StaticMeshAsset
Public function bool

UE::AssetUtils::GetStaticMeshLODMaterialListBySection ( UStaticMesh* StaticMeshAsset,
int32 LODIndex,
TArray< UMaterialInterface* >& MaterialListOut,
TArray< int32 >& MaterialIndexOut
)

 Construct the linear per-section material list for a given LODIndex of a StaticMeshAsset
Public function bool

UE::AssetUtils::ReadTexture ( UTexture2D* TextureMap,
TImageBuilder< FVector4f >& DestImageOut,
const bool bPreferPlatformData
)

 Extract the Dimensions and image pixels from an input TextureMap By default, the "Source" texture data is read.
Public function bool

UE::AssetUtils::SaveDebugImage ( const TArray< FColor >& Pixels,
FImageDimensions Dimensions,
FString DebugSubfolder,
FString FilenameBase,
int32 UseFileCounter
)

 Save image stored in Pixels, of given Dimensions to /Intermediate/DebugSubFolder/FilenameBase_.bmp If UseFileCounter is not specified, an internal static counter that is incremented each call is used.
Public function bool

UE::AssetUtils::SaveDebugImage ( const FImageAdapter& Image,
bool bConvertToSRGB,
FString DebugSubfolder,
FString FilenameBase,
int32 UseFileCounter
)

 Save Image to /Intermediate/DebugSubFolder/FilenameBase_.bmp If UseFileCounter is not specified, an internal static counter that is incremented each call is used.
Public function bool

UE::AssetUtils::SaveDebugImage ( const TArray< FLinearColor >& Pixels,
FImageDimensions Dimensions,
bool bConvertToSRGB,
FString DebugSubfolder,
FString FilenameBase,
int32 UseFileCounter
)

 Save image stored in Pixels, of given Dimensions to /Intermediate/DebugSubFolder/FilenameBase_.bmp If UseFileCounter is not specified, an internal static counter that is incremented each call is used.
Public function void Utility function to apply build settings changes to a UStaticMesh
Public function void Utility functions to preprocess a MeshDescription so that it is suitable for use in Modeling Tools, ie with fully-populated autogen normals/tangents/etc.
Public function void Populate any auto-generated attributes of a FMeshDescription that are currently invalid (eg Normals/Tangents, which may be zero until calculated)
Public function void Populate any auto-generated attributes of a FMeshDescription that are currently invalid (eg Normals/Tangents, which may be zero until calculated)
