Even if you don't get along with the DAZ|Studio interface for regular use, creating a morph and saving it as DUF is quite easy to do, and will work much better than trying to do it from within Poser. Once you've saved it, you can just load Genesis in Poser, and your new morph is always there, ready to use. You're then free to forget about DAZ|Studio until the next time you need to create another morph (or create Poser companion files for a product that doesn't include them - this is even easier than creating morphs).
