In addition to what Jonas posted, you can also acheive geometric dents without purchasing additional IPAS routines by using the boolean function in 3DS. Often you'll need to tessellate objects before doing this, if there aren't any vertices in the area. I'm not sure what the threshold on that is, but a little experimentation will get you a long way. Also, if you don't need geometric dents, then you can always just apply a bump map where the "dents" part of the map would be darker in gray-scale than the rest of the surface map.
