Functions

  Type Name Description
Public function Static void

CopyTextureToRenderTargetTexture ( UTexture* SourceTexture,
UTextureRenderTarget2D* RenderTargetTexture,
ERHIFeatureLevel::Type FeatureLevel
)

 Static: Copies a texture to a render target texture
Public function Static UTexture2D * Static: Creates a temporary texture used to transfer data to a render target in memory
Public function Static bool

DoesMeshComponentUseTexture ( UMeshComponent* MeshComponent,
UTexture* Texture
)

 Checks whether or not the given MeshComponent's materials use the specified texture
Public function Static void

FindMaterialIndicesUsingTexture ( const UTexture* Texture,
const UMeshComponent* MeshComponent,
TArray< int32 >& OutIndices
)

 Tries to find Materials using the given Texture and retrieve the corresponding material indices from the MEsh Compon
Public function Static bool

GenerateSeamMask ( UMeshComponent* MeshComponent,
int32 UVSet,
UTextureRenderTarget2D* SeamRenderTexture,
UTexture2D* Texture,
UTextureRenderTarget2D* RenderTargetTexture
)

 Will generate a mask texture, used for texture dilation, and store it in the passed in render target
Public function Static int32 Returns the maximum bytes per pixel that are supported for source textures when painting.
Public function Static EPixelFormat Returns the pixel format that CreateTempUncompressedTexture uses to create render target data for painting.
Public function Static void

RetrieveMeshSectionsForMaterialIndices ( const UMeshComponent* MeshComponent,
int32 LODIndex,
const TArray< int32 >& MaterialIndices,
TArray< FTexturePaintMeshSectionInfo >& OutSectionInfo
)

 Retrieve LOD mesh sections from MeshComponent which contain one of the Material Indices
Public function Static void

RetrieveMeshSectionsForTextures ( const UMeshComponent* MeshComponent,
int32 LODIndex,
TArray< const UTexture* > Textures,
TArray< FTexturePaintMeshSectionInfo >& OutSectionInfo
)

 Retrieve LOD mesh sections from MeshComponent which use one of the given textures
Public function Static void Retrieves all Paintable Textures from the given MeshComponent
Public function Static void

SetupInitialRenderTargetData ( UTexture2D* InTextureSource,
UTextureRenderTarget2D* InRenderTarget
)

 Makes sure that the render target is ready to paint on
