ok heres how it goes..
i put together a character (using genesis) and added the clothing. (did a render)everything looked good
added lighting and did another render (still ok)
the clothing had visible handles so i reduced the opacity of the handles and did another render well what i ended up with was my model became partially transparent.
removed the clothing rendered and all was well. tried another outfit that i new had visible handles when it loads and rendered. lowered handle opacity and got the same problem. anyone now what i can do or what im doing wrong.
