“This Noesis Interactive tutorial teaches the process of creating custom facial maps using Photoshop. Learn how to take a series of digital photos and edit them together so that they are ready to be mapped onto a 3D game model as a single texture. If you’ve ever wanted to see your own face inside a video game, this is the lesson for you.”
