Think I may have solved it, by selecting V4 then selecting "Figures/Skinning method/Poser Unimesh" and in V4's body properties changing the now enabled "Subdivision levels/Render" to 2. This has cleaned the shadows up, why on earth it takes note of the mesh considering it has no sharp edges at those points is beyond me. perhaps there is another reason.

Getting old and still making "art" without soiling myself, now that's success.
