Functions

Public

Name Remarks Include Path Unreal Specifiers

uint32 AddLayer()

 Add space for a layer in the stack. Returns an index that can be used for SetLayer(). MaterialShared.h  

bool AreLayersFull()

 Returns true if we have allocated the maximum number of layers for this stack. MaterialShared.h  

int32 FindLayer ( int32 UniformExpressionIndex
) const

 Find the layer in the stack that was set with this expression index. MaterialShared.h  

uint32 GetNumLayers()

 Get the number of layers allocated in the stack. MaterialShared.h  

void GetTextureValue ( const FMaterialRenderContext& Context,
const FUniformExpressionSet& UniformExpressionSet,
const URuntimeVirtualTexture*& OutValue
) const

 Get the URuntimeVirtualTexture object if one was used to initialize this stack. MaterialShared.h  

void GetTextureValue ( const FMaterialRenderContext& Context,
const FUniformExpressionSet& UniformExpressionSet,
const USparseVolumeTexture*& OutValue
) const

 Get the USparseVolumeTexture object if one was used to initialize this stack. MaterialShared.h  

void GetTextureValues ( const FMaterialRenderContext& Context,
const FUniformExpressionSet& UniformExpressionSet,
UTexture const** OutValues
) const

 Get the array of UTexture objects for the expressions that in the layers of this stack. MaterialShared.h  

const FTypeLayoutDesc & GetTypeLayout()

   MaterialShared.h  

bool IsPreallocatedStack()

 Returns true if this is a stack that with a preallocated layout of layers (for example when we are using a URuntimeVirtualTexture). MaterialShared.h

uint32 SetLayer ( int32 LayerIndex,
int32 UniformExpressionIndex
)

 Set an expression index at a layer in the stack. MaterialShared.h
