Functions

  Type Name Description
Public function Const InExpressionClass *

CreateExpression ( const FString& InComment,
UObject* InAsset
)

  
Public function Const UMaterialExpression *

CreateExpression ( TSubclassOf< UMaterialExpression > InExpressionClass,
const FString& InComment,
UObject* InAsset
)

 Creates an expression of the given class and adds it to the material.
Public function Const UMaterialExpressionAppendVector *

CreateExpressionAppend ( UMaterialExpression* InExpressionA,
int32 InOutputIndexA,
UMaterialExpression* InExpressionB,
int32 InOutputIndexB
)

 Creates an append expression, joining the output of 2 other expressions into a single vector.
Public function Const UMaterialExpressionComponentMask *

CreateExpressionBitMask ( UMaterialExpression* InExpression,
int32 InOutputIndex,
int32 InOutputChannels
)

 Creates a set of expressions merging all the inputs for each channel into a single output
Public function Const TArray< UMaterialExpression * >

CreateExpressionInput ( UDMMaterialStageInput* InInput
)

 Creates a set of expressions that display this material stage input.
Public function Const TArray< UMaterialExpression * >

CreateExpressionInputs ( const TArray< FDMMaterialStageConnection >& InInputConnectionMap,
int32 InStageSourceInputIdx,
const TArray< UDMMaterialStageInput* >& InStageInputs,
int32& OutOutputIndex,
int32& OutOutputChannel
)

 Creates a set of expressions merging all the inputs for each channel into a single output
Public function Const InExpressionClass *

CreateExpressionParameter ( FName InParameterName,
EDMMaterialParameterGroup InParameterGroup,
const FString& InComment,
UObject* InAsset
)

  
Public function Const UMaterialExpression *

CreateExpressionParameter ( TSubclassOf< UMaterialExpression > InExpressionClass,
FName InParameterName,
EDMMaterialParameterGroup InParameterGroup,
const FString& InComment,
UObject* InAsset
)

 Creates an expression of the given class as a parameter and adds it to the material.
Public function Const void

UpdatePreviewMaterial ( UMaterialExpression* InLastExpression,
int32 InOutputIndex,
int32 InOutputChannel,
int32 InSize
)

 Updates a preview material, assigning the output of the "last expression" to an appropriate material property.
