These videos are for PES (Pro Evolution Soccer). You may find them helpful for making cyberfaces. Cyberfaces for PES and FIFA are similar to NBA 2K. They just use different tools to import/export the graphic files. There are also blender and photoshop (and GIMP and Paint Shop Pro) tutorials on YouTube. These tutorials may not be specific to NBA 2K but they can be helpful to learn techniques.
