The $displacementmap command is an alternative to $bumpmap that uses a heightmap to give the illusion of depth.
It's the most realistic of all the texture shadowing techniques, but consequently is also the most expensive.
It requires a model compiled with $subd. For best results use a relatively high tessellation level.
