Texturing was done neither in ZBrush by actually hand painting color and texture onto the models in real-time. I painted these onto the high poly versions of the meshes, so in order to get a color map from the painting I have done, I had to bake out the texture. I've also baked out normal maps and ambient occlusion maps so I can combine these and apply them to the low-poly versions of the models'.
I wanted to practice this, hence I`ve created all of the garment models (flags and Kael'thas robe) in low poly and painted the wrinkles and folds into the texture. There are numerous ways of doing this. I`ve chosen the burn and dodge tool found within Photoshop to darken and lighten up the necessary areas to create the illusion of folds. They actually worked :) .
