I would like to add a light or modest amount of thin blue vein detail to some areas of V4 for the sake of realistic detail, but can't find anything in DS4 to do that.

I've seen large vascular detail in M4  in a few renderings who's naturally supposed to be more muscular of course, and maybe 2-3 at the most in She-Freak/Amazon female renders, but that's it. And that's not what I'm after anyway. I'm wanting realistic thin blue veins for upper chest & neck area, lower leg area and arm & hands. Just slightly larger veins for forearm & hands. I'm not rendering a female bodybuilder, just a petite, feminine, early 20s young woman. I've been thinking lately that a modest or slight amount of vascularity for women is the one thing that's missing in 99+% of the V4, S4 & A4 models out there.

How do you do that in DS4? Or can it be done in Poser?
