I updated to SDK19 on my dev laptop and blender live model reload is not working again. I can only get my live reload to work in the sim if I open the gltf in notepad++ and save it there. Then it will reload in the sim. Just exporting from the Asobo exporter will not get it to reload even though the exporter is writing all the files correctly (I looked at the time stamps). This was working fine on SDK 18 on my home computer just a few days ago. Can anyone else verify?
