Blender to pov or obj

I have some obj models that I modified in blender. I want to render
them in povray. I can export them as obj using
that I got from blenders site. I then use PoseRay to convert from obj
to povray. The problem is the python script does not seem to export
the smoothing angle “Auto Smooth in blender”. I also need to export
the file as a vrml for online realtime viewing. Blender natively
supports this but it doesn’t export the smoothing angle either. Is
there an exporter that will export the smoothing angle? It is
important, so I don’t know why it would be left off. Thank you.

P.S. I am new to blender.
