I'm no export on POVRay either I'm afraid, in fact I don't think I've ever run the program. I used the POVRay format as an intermediary for exporting models so I could pull them into 3dsmax with a povray import maxscript. This was before I wrote the maxscript export option of course.
I basically wrote out the pov file in the same format as mitselplik's EQZoneConverter files came out, I just presumed those rendered in POVRay correctly
