>>>> If your goal is to use Victoria 4 in DAZ Studio, it may help to first find people who are still actively using that workflow. They are likely to have the practical experience you're looking for.
It's easy enough to load V4 into DAZ Studio. I installed her into DAZ Studio using DAZ Install Manager. Her CR2 ended up being locaed in "My DAZ 3D Library > Runtime > Libraries > Character > DAZ People", along with other generation 4 characters like Aiko 4, Hiro 4, Michael 4, and others.
As far as rigging goes, I've already explained to bluewoods in PM's that rigging takes literally MONTHS to learn. It's a lot to expect one person to answer every possible question in private correspondence, because it is very involved. I tried to help bluewoods privately and spent five hours going back and forth, because one question led to another, and another, and another. But given that it will take a good 2-3 months to learn rigging, it's too much to expect one person to answer the many questions that will no doubt arise when learning rigging. Every piece of clothing presents different challenges.
Rigging is a topic that is best handled in the forums, where other people can contribute and benefit from the responses.
I have bluewoods on ignore at the moment because the questions got to be too much. I will only ask again to be respectful of other people's time and to be patient with learning because it is very involved. With that, I'm out of this discussion.
