Something I forgot to mention in my last posting -

Needless to say, the 'walls' solution will add a lot of raster work to your
application, and will make it fill limited (which I suppose it already is,
running on an XZ). In that case you might want to do some selective drawing of
the walls, meaning you will draw them only on tiles that have a lower (higher)
LOD neighbour. YOu can implement this by having each tile duplicated under a
pfSwitch - one copy will have the walls and the other will not. Before drawing
you will have to decide which copy will be drawn for each switch.
