David, After looking into Paul's suggestion, I believe that (for static terrain) if you add your terrain to your scaling node, and then use Paul's suggestion on the scaling node, you may get what you're looking for. The Optimizer is much simpler than my original suggestion, although you may still want to look at those other classes for future work.
Again, if your terrain has levels of detail, I would recommend just using the MatrixTransform approach. I hope this helps... D.J.
