 Babylon.js exporters
 ====================
 
+NOTE - The Babylon.js Exporters are no longer in active development. While the tools will continue to work for existing versions of Maya & Max (2022), we cannot guarantee that they will continue to work for future versions. If you are interested in helping us maintain these tools for future versions of Maya & Max, we'd GLADLY welcome the help, please contact us on the [Babylon.js Forum](https://forum.babylonjs.com/)
