Remarks

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

Returns

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

Parameters

Parameter	Description
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
