im sure that there are a lot of you who have used crazy bump
and the time limit ran out and you found your self limping a bit.
well even though the price is well worth it, there is a cheaper alternative
free even if you dont mind a little work.
the pro is 20 dollars us
and they even provide a non commercial command line version that does the same as the graphical one.
which is free.
all you have to do is dload them both (not huge)
and use the gui to preview and adjust until you get it just right.
them transfer those settings to a batch file to call the command line version.
you have the textures you see and crave from your diffuse original.
they provide example batfiles to get you going and the online doc is good.
anyway thought i would share
