Hello community

right now I’m creating an application to convert a obj file … to j3o.

the convert successful, but don’t create with the material (.mtl) the object is dark (attached image)

The code for the convert is:

[java]
model = refApp.getAssetManager().loadModel(files[i].getName());

            String nombre = files[i].getName();
            String[] nombresolo = nombre.split("\\.");


            File destDir = new File(nombreCarpetaj3o1);
            Path destPath = destDir.toPath();


            BinaryExporter exporter = BinaryExporter.getInstance();
            File file = new File(destPath + "/" + nombresolo[0] + ".j3o");
            try
            {
                exporter.save(model, file); //model is a Spatial 
            }
            catch (IOException ex)
            {
                System.out.println("exception: " + ex);
            }

[/java]
the model variable is a Spatial.

What is the problem?

Thank you
