InExpressionClass * CreateExpression ( const FString& InComment,
UObject* InAsset
) const

   Model/IDMMaterialBuildUtilsInterface.h  

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

 Creates an expression of the given class and adds it to the material. Model/IDMMaterialBuildUtilsInterface.h  

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

 Creates an append expression, joining the output of 2 other expressions into a single vector. Model/IDMMaterialBuildUtilsInterface.h  

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

 Creates a set of expressions merging all the inputs for each channel into a single output Model/IDMMaterialBuildUtilsInterface.h  

TArray< UMaterialExpression * > CreateExpressionInput ( UDMMaterialStageInput* InInput
) const

 Creates a set of expressions that display this material stage input. Model/IDMMaterialBuildUtilsInterface.h  

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

 Creates a set of expressions merging all the inputs for each channel into a single output Model/IDMMaterialBuildUtilsInterface.h  

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

   Model/IDMMaterialBuildUtilsInterface.h  

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

 Creates an expression of the given class as a parameter and adds it to the material. Model/IDMMaterialBuildUtilsInterface.h  

int32 FindOutputForBitmask ( UMaterialExpression* InExpression,
int32 InOutputChannels
) const

 Searches the outputs of an expression to see if there is an appropriate output to match a requested channel mask. Model/IDMMaterialBuildUtilsInterface.h  

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

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