CreateTextureExpression()

IDatasmithMaterialExpressionTexture * DatasmithMaterialsUtils::CreateTextureExpression	(	const TSharedRef< IDatasmithUEPbrMaterialElement > &	MaterialElement,
		const TCHAR *	ParameterName,
		const TCHAR *	TextureMapPath,
		const FUVEditParameters &	UVParameters
	)

Generate material expressions on a given DatasmithUEPbrMaterialElement to output a texture with UV settings applied to it

Parameters

MaterialElement	The UEPbrMaterialElement on which to create the material expressions
ParameterName	The display name for the Texture expression
TextureMapPath	The texture to use for the Texture expression
UVParameters	The UVEditParameters to apply

Returns

Texture expression with UVEdit applied to it; nullptr if no TextureMapPath is specified

CreateWeightedMaterialExpression()

IDatasmithMaterialExpression * DatasmithMaterialsUtils::CreateWeightedMaterialExpression	(	const TSharedRef< IDatasmithUEPbrMaterialElement > &	MaterialElement,
		const TCHAR *	ParameterName,
		TOptional< FLinearColor >	Color,
		TOptional< float >	Scalar,
		IDatasmithMaterialExpression *	Expression,
		float	Weight,
		EDatasmithTextureMode	TextureMode = EDatasmithTextureMode::Diffuse
	)

Generate material expressions on a given DatasmithUEPbrMaterialElement that output a color or scalar interpolated with a MaterialExpression

Parameters

MaterialElement	The UEPbrMaterialElement on which to create the material expressions
ParameterName	The display name for the Color or Scalar input
Color	The color to interpolate the Expression with. If no color is given, use the scalar
Scalar	The scalar to interpolate the Expression with. If no color or scalar are given, use the Expression only
Expression	The MaterialExpression to interpolate the Color or Scalar with
Weight	The weight of the Expression in the interpolation
TextureMode	The TextureMode of the Expression to determine if it requires normal flattening (bump and normal mode) or interpolation

Returns

Material expression that outputs a Color or Scalar interpolated with Expression; nullptr if no Color, Scalar or Expression are given
