“This is not a step by step tutorial. I will summarize the workflow I used for one of my characters with lots of images and some print-screens directly from the applications used (maya/mudbox/photoshop etc …), also in the end I will provide some info about tangent space normal maps so you could think of this tutorial as mainly normal mapping related stuff.”
