Syntax
class IDatasmithMaterialExpression : public IDatasmithElement
Remarks
Base class for representing an expression in the material graph of a IDatasmithUEPbrMaterial. Setting a name to the expression is optional but allows to automatically create material instances during the import, which is faster and more optimal.
