In this beta version, experimental support of Levels. You need to export the model using the latest version of the ExportToHass plugin (Download)
Also exeperimental support of glb format (imports only the scene objects, no animation or other assets). I intend to develop this format further as it is providing a lightning fast model loader, maybe in the future also for integrating blender animations or other funny stuff.
Once you have exported to hass using my plugin, you will end up with a zip with all the files of the obj format: you can use this program to convert to glb (will try to do a tutorial in the coming days). Using this flow you will obtain a result that is very close to the usual obj format flow, there are still some bug though. Give it a try.....
