Oddball thought that's hit me recently, that would probably ruffle feathers in the DAZ forums because it would be seen as a complaint and then I'd be innundated with reasons why. I know why.
But I really hate it when clothing is a geograft. I know why some vendors do it, and as of yet, I haven't encountered a single outfit done like this where it didn't make sense. But I've got a habit of loading in 3-4 pairs of jeans, for example, and then hiding and showing them to see which I like best with a particular top. And geografted jeans don't handle that well.
Also, it makes it difficult if I want to set the sleeves to 0% opacity, so that I can make the shirt sleeveless.
And it doesn't allow for things like ripped knees, since there's no knee to show through.
I've found a couple of ways around it, and so far none of them have bit me in the butt.
I still don't like it, though.
