continuing on from my beginer tutorial, this tutorial explores alternitive ways to building textures in photoshop more suitable to more constructive texture creating. alpha maps for opacity are covered. as well as photoshop, crazybump is used in this tutorial but is not vital. you can get away with just using the Nvidia plug-in, xnormal or any other of type. this tutorial is 27 pages long, so there is plenty to work through.
