By default, babylon.js comes with an importer for .babylon files.

You can also create your own importer by providing a specific object to the BABYLON.SceneLoader.RegisterPlugin function.

This object must have three properties:

• A list of supported file extensions (extensions)
• An importMesh function to import specific meshes
• A load function to import complete scene

Here is a sample importer object:

    BABYLON.SceneLoader.RegisterPlugin({
        extensions: ".babylon",
        importMesh: function (meshesNames, scene, data, rootUrl, meshes, particleSystems, skeletons) {
            return true;
        },
        load: function (scene, data, rootUrl) {
            return true;
        }
    });

• meshesNames is the names of meshes to import
• scene is the scene to load data into
• data is the string representation of the file to load
• rootUrl defines the root URL of your assets
• meshes is the list of imported meshes
• particleSystems is the list of imported particle systems
• skeletons is the list of imported skeletons
