Detailed Description

Declaration of external HLSL code. Such code expressions can be emitted as part of a material translation.

Member Function Documentation

GetReturnTypeValue()

EMaterialValueType FMaterialExternalCodeDeclaration::GetReturnTypeValue ( ) const

inline

Function return type as material value type. Deduced from ReturnType string to maintain compatibility with other systems that rely on EMaterialValueType not being a UENUM().

UpdateHash()

void FMaterialExternalCodeDeclaration::UpdateHash

(

FSHA1 &

Hasher

)

const

Updates the input hasher state with the content of this external code declaration.

Member Data Documentation

bIsInlined

uint32 FMaterialExternalCodeDeclaration::bIsInlined

Definition

FString FMaterialExternalCodeDeclaration::Definition

Primary external code definition provided as HLSL shader code expression.

DefinitionDDX

FString FMaterialExternalCodeDeclaration::DefinitionDDX

Secondary external code definition for custom DDX derivatives.

DefinitionDDY

FString FMaterialExternalCodeDeclaration::DefinitionDDY

Secondary external code definition for custom DDY derivatives.

Derivative

EDerivativeStatus FMaterialExternalCodeDeclaration::Derivative = EDerivativeStatus::NotAware

Specifies the kind of derivative this code declaration provides. If this is EDerivativeStatus::Valid, DefinitionDDX and DefinitionDDY provides the code definitions for the DDX and DDY derivatives respectively.

Domains

TArray<TEnumAsByte<EMaterialDomain> > FMaterialExternalCodeDeclaration::Domains

List of material domains this external code can be used with. If this is empty, all material domains are accepted.

EnvironmentDefines

TArray<FMaterialExternalCodeEnvironmentDefine> FMaterialExternalCodeDeclaration::EnvironmentDefines

List of shader environment defines to enable for this external code declaration.

MinimumFeatureLevel

EMaterialFeatureLevel FMaterialExternalCodeDeclaration::MinimumFeatureLevel = (EMaterialFeatureLevel)0

Minimum required feature level for this external code.

Name

FName FMaterialExternalCodeDeclaration::Name

ReturnType

EMaterialValueTypeBridge FMaterialExternalCodeDeclaration::ReturnType = EMaterialValueTypeBridge::Unknown

ShaderFrequency

EMaterialShaderFrequency FMaterialExternalCodeDeclaration::ShaderFrequency = EMaterialShaderFrequency::Any
