You would almost certainly need Morphs++ for V4, that gives you access to lots of morphs to change the shape of the Nose, Mouthm Lips, Brow, Cheeks, eyes etc etc.
I have never heard of a blank template, do you mean like a totally featureless face, to add detail to? I have never seen one, most people would start with the basic V4 model, and go from there.
I have got Morphs++ thanks but the biggest problem for me anyway is you’re always working from an existing or someone else’s artwork rather than from scratch so I suppose it would be some sort of blank featureless template/ face if that’s possible ? Personally I’ve always found altering or overwriting other people’s drawings very overpowering and distracting and why I always outline what I personally want first when still very unsure or unclear starting with very hard 6H pencils on a blank sheet of paper gradually refining it down to softer leads of about 3H. It’s because you can hardly see anything with a 6H lead especially when pressing down normally that it’s great for getting the basic non-distracting outline first which then illustrates and then brings forth the actual picture/ sketch itself. You then choose progressively harder and harder leads to firm up the chosen outline till you’re almost there. Sometimes there can be so many lines it gets just too messy to continue with so I then use tracing paper to “lock” the final idea and details into place. There are many other in-between bits and pieces you can do but when ready and last of all you use very soft leads 3B upwards to about 6B for shading.
I’ve never heard of a blank template either though I’ve never looked before but the next problem would be how does one then get it on the Daz screen itself ??
