No. the technique makes use of a paint program, taking an orthographic 
overhead image of the scene as basis, and painting the dirt in shades of 
grey on a separate layer, then applying that layer image as a 
height_field in the original scene, superposed if necessary over a 
pre-existing height_field or other surface.

It is a business that needs close attention but far from impossible and, 
using a paint program in conjunction with a height_field generator, it 
can even make more interesting features.
