Variables

  Type Name Description
Public variable int32[8] LayerUniformExpressionIndices Indices of the expressions that were set to layers in this stack.
Public variable uint32 NumLayers Number of layers that have been allocated in this stack.
Public variable int32 PreallocatedStackTextureIndex Index of a texture reference if we create a stack from a single known texture that has it's own layer stack.

Constructors

Public function    
Public function  

FMaterialVirtualTextureStack ( int32 InPreallocatedStackTextureIndex
)

 Construct with a texture index when this references a preallocated VT stack (for example when we are using a URuntimeVirtualTexture).

Functions

  Type Name Description
Public function uint32 Add space for a layer in the stack.
Public function Const bool Returns true if we have allocated the maximum number of layers for this stack.
Public function Const int32

FindLayer ( int32 UniformExpressionIndex
)

 Find the layer in the stack that was set with this expression index.
Public function Const uint32 Get the number of layers allocated in the stack.
Public function Const void

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

 Get the URuntimeVirtualTexture object if one was used to initialize this stack.
Public function Const void

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

 Get the USparseVolumeTexture object if one was used to initialize this stack.
Public function Const void

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

 Get the array of UTexture objects for the expressions that in the layers of this stack.
Public function Const const FTypeLayoutDesc &  
Public function Const bool Returns true if this is a stack that with a preallocated layout of layers (for example when we are using a URuntimeVirtualTexture).
Public function void  
Public function uint32

SetLayer ( int32 LayerIndex,
int32 UniformExpressionIndex
)

 Set an expression index at a layer in the stack.
Public function Static FTypeLayoutDesc &
