The Purple Bikini the fix has been there all along. I forget what arcane web tut I found this but the bikini can be ignored!
When using the v4 power loader (DAZ3) a dialog window comes up with Basic and Advanced Tabs
Click Advanced Tabs
inside that is another set of tabs
notice ittybitty checkbox in upper left corner-click it where it says Load Presets
There should be three choices with circles in front
All Natural with Bikini (the default)
All Natural No Gens
I click the 3rd and Accept
You will see the Loader loading up V4 morphs + etc and to your dismay you will see behind the status window that purple bikini
Fear Not! After all the loading is done
Voila She Appears Sans Bikini!
Sorry I don’t know how to do the screen capture for this.
I’ve noticed sometimes I can see through the eyeballs too. I think one can select a different a “different drawstyle for the selected port” with one of the big round buttons near the View selector box. One of those styles may be more familiar for you while working in with the model before rendering.
