Exporting an fbx or obj from Unity 5

Anyone have any recommendations for exporting a single object from Unity5? I need to bring a mesh into BitmapToMaterial for previewing materials. Any of the free options I’ve tried don’t work.
ie when I load the mesh in BitMapToMaterial I see nothing!

I’ve tried
Scene Object Exporter

and also this ExportObj script from the wiki

Go to your project folder.

“your project folder”\Assets\

drag and drop the .fbx file. Be sure not to drag the meta files along.
