I too have learned to make morphs using the D-Former tool. The whole thing can actually be done within the DAZ Studio app. The ones I have made are for Genesis’ head and ears. I have many more planned. I am working in DS4.5 Pro now and I have found that it is different from earlier versions that offered the D-Former feature. I do have DS 3 Advanced and DS 4.0 Pro available to me but I hardly ever use them anymore. lol
I found several tutorials other than this one that when I combined what I learned from them with what I got from this thread, The ease of making morphs became clear to me. This to me is one of the most fantastic features of DAZ Studio! Thanks for the generous sharing of information.
