I knew it would come down to this in the end. :-(

I found a problem with the Mesh2 output. It is defining the 
face_indices, section. Like this.

     face_indices {

         80,

         <0,13,12>, 0,0,0,

         <1,13,15>, 0,0,0,

I don't know what PovRay makes of that. Bishop3D threw a wobbly when it 
tried to import it.

I've raised a ticket with mr.

Thanks for thinking about it.
