When the suit is at full transparency, and with the edge falloff at default value, the suit isn't at full invisibilty. Some of it still renders.  Otherwise I have specular highlights set at 3%.

As for the textures. I don't dispute there may be otherways to go, but this is the way I thought of after studying the DAZ V4 bodysuit. I figured if it was good enough for them it would work for me. Even if it's not the way DAZ did it, it's working for me, so I'll stick with it.  If the end user knows a better way to deal with it let them have at it. They have that option.
