This might be useful, unless you're only convinced 100% procedural rendering of the terrain is the grooviness.

Interesting...
Still looks a bit flat though.
Did you try it? You get 5 (or is it 6?) maps after you run an image through. Everything depends on your settings.
Not so comfortable bur working: Gimp an the normalmap plugin, http://nifelheim.dyndns.org/~cocidius/normalmap/
With the new raytracer for objects you can't render objects anymore with real displacements. Instead the displacement image/function will be interpreted as a bump image/function.
So there's no added geometry but it's being mimiced.
About a year ago Crazybump wasn't compatible with 64-bit windows, now it is :)
I've have obtained quite nice results using this easy piece of software to get nice bump-maps as well as specularity masks, which work nice with the new raytracer.
Will post some results after the weekend.

I tried the GIMP one but I don't have a clue where it put itself! >:( ???
