In a Mudbox plug-in you can load or save plug-in data with the scene by overloading the Node::Serialize() method. Mudbox will call Node::Serialize() method with an initialized Stream object. You can then query Stream::IsStoring() to implement the saving or loading application logic, depending on whether the return value is true or false respectively.

Any attributes you create in a plug-in that you wish serialized with the scene will have to be manually serialized. For example:

  MyPlugin : Node

  {

    Attribute A;

    Attribute B;

  public:

    MyPlugin::Serialize(Stream& s) {

      f ( s.IsStoring() )

        s << A << B;

      else

        s >> A >> B;

    }

  };

The Mudbox SDK also provides an overload of the operator== to mean Node::Serialize(). So alternatively you can write:

  MyPlugin : Node

  {

    Attribute A;

    Attribute B;

  public:

    MyPlugin::Serialize(Stream& s) {

      s == A == B;

    }

  };
