Smoothing not working from blender

Smoothing not showing after exporting from blender. I dont know why?

Can you post an image please .I cannot get what you are trying to say.

what you can do is when you export your model from blender you change smoothing group from normals to faces.
the option is present in the geometry tab.
and here is the documentation.Hope this helps
