In this Xenosmash tutorial we will once again be creating normal maps for use in our scenes but this time we will be creating them using a program called Crazy Bump. The beta version for Mac is used in this tutorial (which is free at the moment). Crazy bump is available for PC and Mac at www.crazybump.com
Textures can be found at http://www.cgtextures.com/
