Functions

Public

Name Remarks Include Path Unreal Specifiers

void Clear()

 Releases any memory allocated by the Texture Synthesis object MetaHumanFaceTextureSynthesizer.h  

FVector3f GetBodyAlbedoGain ( const FVector2f& InUV
) const

 Gets the body albedo gain for a given Skin UV value MetaHumanFaceTextureSynthesizer.h  

const FMetaHumanFaceTextureAttributeMap & GetFaceTextureAttributeMap()

 Gets the texture attribute map associated with the face texture synthesizer. MetaHumanFaceTextureSynthesizer.h  

int32 GetMaxHighFrequencyIndex()

 Get the maximum value for the HF index the model supports MetaHumanFaceTextureSynthesizer.h  

FLinearColor GetSkinTone ( const FVector2f& InUV
) const

 Gets the Skin Tone for a given Skin UV value MetaHumanFaceTextureSynthesizer.h  

TArray< EMapType > GetSupportedAlbedoMapTypes()

 Returns the albedo map types that can be synthesized by this model (without input HF maps) MetaHumanFaceTextureSynthesizer.h  

TArray< EMapType > GetSupportedNormalMapTypes()

 Returns the normal map types that can be selected by this model MetaHumanFaceTextureSynthesizer.h  

EGammaSpace GetTextureColorSpace()

 Color space of the generated textures MetaHumanFaceTextureSynthesizer.h  

ERawImageFormat::Type GetTextureFormat()

 Image format of the generated textures MetaHumanFaceTextureSynthesizer.h  

int32 GetTextureSizeX()

 Size of the generated Textures along the first dimension MetaHumanFaceTextureSynthesizer.h  

int32 GetTextureSizeY()

 Size of the generated Textures along the second dimension MetaHumanFaceTextureSynthesizer.h  

bool Init ( const FString& InTextureSynthesisFolderPath,
int32 InNumThreads
)

 Initialize the Texture Synthesis object by loading all the necessary model data from the MetaHumanCharacter content InTextureSynthesisFolderPath should point to a folder with the texture synthesis model data as used by the UE data loader InNumThreads is the number of threads to use for each texture synthesis map, pass 0 for single thread synthesis MetaHumanFaceTextureSynthesizer.h  

bool IsValid()

 Returns whether the Texture Synthesis object has been initialized and the internal model data are valid MetaHumanFaceTextureSynthesizer.h  

FVector2f ProjectSkinTone ( const FLinearColor& InSkinTone,
const int HFIndex
) const

 Projects a skin tone to the texture model and returns the Skin UV Value The returned UV value is clamped to [0,1] if the input skin tone is projected outside the bounds what the texture model can represent. MetaHumanFaceTextureSynthesizer.h  

bool SelectCavity ( int32 HighFrequencyIndex,
FImageView OutCavityImage
) const

 Select the cavity texture map to be used for this HF index OutCavityImage should be pre-allocated with the appropriate size and format MetaHumanFaceTextureSynthesizer.h  

bool SelectNormal ( const FTextureSynthesisParams& InTextureSynthesisParams,
FImageView OutNormalImage
) const

 Select a normal texture map based on the input parameters OutNormalImage should be pre-allocated with the appropriate size and format MetaHumanFaceTextureSynthesizer.h  

bool SynthesizeAlbedo ( const FTextureSynthesisParams& InTextureSynthesisParams,
FImageView OutAlbedoImage
) const

 Synthesize an albedo texture map with the input parameters and store in the passed ImageView object OutAlbedoImage should be pre-allocated with the appropriate size and format MetaHumanFaceTextureSynthesizer.h  

bool SynthesizeAlbedoWithHF ( const FTextureSynthesisParams& InTextureSynthesisParams,
const TStaticArray< TArray< uint8 >, 4 >& InHFMaps,
FImageView OutAlbedoImage
) const

 Synthesize an albedo texture map using the input HF maps OutAlbedoImage should be pre-allocated with the same target resolution of the input HFMap and this model output format MetaHumanFaceTextureSynthesizer.h
