Google is not the only one that's good at maps

Check this out. ProFX and MaPZone seem to allow procedural texturing on the fly, so that you don't need the gigabytes of textures to ship with your game. More than that, MaPZone can make diffuse, specular, normal, and other maps all fit together effortlessly. Alright, I'm interested. Oh, and did I mention they are an XNA partner, so they have a special (read dumbbed down) version of MaPZone free. Did I mention I was interested?
