I have finally finished my first attempt at a set of nipple morphs for Antonia 114. I doubt that the set of polygons I used for the nipple walls is the one intended by odf. I think I probably went one ring inside that. Any way I might do another morph set in the future, using different polys for the walls, but I may wait to see how the new UVs and textures turn out before making another set.  The above graphic shows how I visualised the areolae and nipples when making the morphs.
