class UMaterialExpressionTextureSampleParameter : public UMaterialExpressionTextureSample

Type	Name	Description
FParameterChannelNames	ChannelNames
FGuid	ExpressionGUID	GUID that should be unique within the material, this is used for parameter renaming.
FName	Group	The name of the parameter Group to display in MaterialInstance Editor. Default is None group
FName	ParameterName
int32	SortPriority	Controls where the this parameter is displayed in a material instance parameter list.

	Type	Name	Description
		UMaterialExpressionTextureSampleParameter ( const FObjectInitializer& ObjectInitializer )

Type	Name	Description
void	ApplyChannelNames ()
FParameterChannelNames	GetTextureChannelNames ()
void	SetDefaultTexture ()	Sets the default texture if none is set
bool	SetParameterValue ( FName InParameterName, UTexture* InValue, EMaterialExpressionSetParameterValueFlags Flags )
bool	TextureIsValid ( UTexture* InTexture, FString& OutMessage )	Return true if the texture is a movie texture

Type	Name	Description
bool	CanRenameNode ()	Can this node be renamed?
int32	Compile ( FMaterialCompiler* Compiler, int32 OutputIndex )	Create the new shader code chunk needed for the Abs expression
bool	GenerateHLSLExpression ( FMaterialHLSLGenerator& Generator, UE::HLSLTree::FScope& Scope, int32 OutputIndex, UE::HLSLTree::FExpression const*& OutExpression )
void	GetCaption ( TArray< FString >& OutCaptions )	Returns the text to display on the material expression (in the material editor).
FString	GetEditableName ()	Returns the current 'name' of the node (typically a parameter name).
FGuid &	GetParameterExpressionId ()	Callback to access derived classes' parameter expression id.
FName	GetParameterName ()
bool	GetParameterValue ( FMaterialParameterMetadata& OutMeta )
bool	HasAParameterName ()	Parameter Name functions, this is requires as multiple class have ParameterName but are not UMaterialExpressionParameter due to class hierarchy.
bool	MatchesSearchQuery ( const TCHAR* SearchQuery )	MatchesSearchQuery: Check this expression to see if it matches the search query
void	SetEditableName ( const FString& NewName )	Sets the current 'name' of the node (typically a parameter name) Only valid to call on a node that previously returned CanRenameNode() = true.
void	SetParameterName ( const FName& Name )
bool	SetParameterValue ( const FName& Name, const FMaterialParameterMetadata& Meta, EMaterialExpressionSetParameterValueFlags Flags )
void	ValidateParameterName ( const bool bAllowDuplicateName )
