Hm..  Ben doesn't have any material-zones between lips and face... it is only a face.  Maybe I need to repaint on the texture map directly 🤔 or work with a 2nd layer only for this part of the face. ..... oh wow.... even more to learn 😅 

I think it is because of some light blue veins, similar on the eye lids, they are also a bit blue.

Yes, I made the materials to apply on all figures... I don't think I will work with the other older figures but Ben. 😊 It is really impressive to see how good they can look, even if they are this old. Ben was in Poser 7.
