FWeightedMaterialExpressionParameters ( float InWeight )		DatasmithFacadeMaterialsUtils.h

Name	Type	Remarks	Include Path
Color	TOptional< FLinearColor >	BHasColor used to emulate TOptional<> behavior, if bHasColor is false, the Color parameter will be ignored.	DatasmithFacadeMaterialsUtils.h
Expression	FDatasmithFacadeMaterialExpression	Local copy of the optional FDatasmithFacadeMaterialExpression.	DatasmithFacadeMaterialsUtils.h
Scalar	TOptional< float >	BHasScalar used to emulate TOptional<> behavior, if bHasColor is false, the Scalar parameter will be ignored.	DatasmithFacadeMaterialsUtils.h
TextureMode	FDatasmithFacadeTexture::ETextureMode		DatasmithFacadeMaterialsUtils.h
Weight	float		DatasmithFacadeMaterialsUtils.h

Name	Remarks	Include Path
