the reason I said that..was having problems with some other stuff going into Vue from Poser...Vue does something with the trans maps... There is a channel to apply transparency..you can also invert it in there... Check this..maybe iots not the invert note the first image is kinda what you have by using fuzzy and additve in the material editor, it looks more transparent. I'm pretty new with Vue myself...have been trying different setings to see what they do...

Humankind has not woven the web of life. We are but one thread within it.
