If we ARE talking about getting tattoos or body painting (or badges onto clothes) on Poser models, rather than on real people, it is done via the texture map. And you will run into snags where the mapping onto the texture map is distorted. For example, it is impossible to get a shoulder badge onto a standard Poser figure with the arms split between the chest and the back. That is why my figure models are texture-mappe with each arm separate and split along the underside only, and that is how I can give men shouder badges in my Sea Patrol pictures (see this link).
