I'm not usually a fan of using 3D paint tools; I find I have much more control when I paint in 2D. However, considering the amount of finer details I sculpted into Caruso's Normal map, it made sense to use Mudbox's painting tools to give the mesh some flat colour to help me visualise the final texture and also as a guide for painting in the details that do not have their own mesh (e.g. the belt, shirt, hair...)
