Export objects from blender and convert them with glow

I am trying to convert Gltf files in the JME SDK, but they have an emission/glow in the export. But as soon as I convert the model, the glow is gone, even though the texture is saved in the file. Can I somehow have the glow in the object so that it remains when converting?

Are you using Blender, can I have screenshot of the shader node of the object in the Blender?
