Hi Phil, I would write a custom Registry::ReadFileCallback that loads the models using the standard Registry::readFileImplementation() way and then runs a custom visitor on the loaded model before returning this model to application.
The custom visitor would look for nodes in the scene graph that are animated and then toggle their state to the state you want, and potentially add extra callbacks or mapping so that you application can keep track of these animating nodes.
