Syntax

class FMaterialVirtualTextureStack

Variables

	Name	Description
int32[8]	LayerUniformExpressionIndices	Indices of the expressions that were set to layers in this stack.
uint32	NumLayers	Number of layers that have been allocated in this stack.
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

	Name	Description
	FMaterialVirtualTextureStack()
	FMaterialVirtualTextureStack ( int32 InPreallocatedStackTextureInd... )	Construct with a texture index when this references a preallocated VT stack (for example when we are using a URuntimeVirtualTexture).

Functions

	Name	Description
uint32	AddLayer()	Add space for a layer in the stack.
bool	AreLayersFull()	Returns true if we have allocated the maximum number of layers for this stack.
int32	FindLayer ( int32 UniformExpressionIndex )	Find the layer in the stack that was set with this expression index.
uint32	GetNumLayers()	Get the number of layers allocated in the stack.
void	GetTextureValue ( const FMaterialRenderContext& Cont..., const FUniformExpressionSet& Unifo..., const URuntimeVirtualTexture*&... )	Get the URuntimeVirtualTexture object if one was used to initialize this stack.
void	GetTextureValues ( const FMaterialRenderContext& Cont..., const FUniformExpressionSet& Unifo..., UTexture2D const** OutValu... )	Get the array of UTexture2D objects for the expressions that in the layers of this stack.
const FTypeL...	GetTypeLayout()
bool	IsPreallocatedStack()	Returns true if this is a stack that with a preallocated layout of layers (for example when we are using a URuntimeVirtualTexture).
void	Serialize ( FArchive& Ar )
uint32	SetLayer ( int32 LayerIndex, int32 UniformExpressionIndex )	Set an expression index at a layer in the stack.
FTypeLayoutD...	StaticGetTypeLayout()
