yes I have "Optitex" as well but it does not work as it did i DAZ3 it will not be fixed untill people stop buying it and yes it depends on where you get the clothing from, if you got it from DAZ then it most likely will load it does for me but what i get from Optitex will not only not load but crashy daz4 so everything saves wit optitex has to be redone and not saved.  The other sad part about optitex is that you have to get only their stuff it will not work on anything unless it's  code is in the prop so i am still looking and praying someone will be kind to us and make a plugin for us untill then oooooohhh wellllllllll
