Update: At this moment, I would not recommend using the EZSkin3 principlebsdf cycles method to enhance the skin texture on any character. I have come across a serious error where the shader does not apply correctly between the arms and the torso. It appears that something is getting internally broken at that point. I have seen it with V4. La Femme, and M4. Oddly, the legs appear fine, considering that they are from the same map.
