What's the best way of posing Elizabeth's long skirts - primarily with the Daz 5-5 version? I've been toying with them for a while and haven't figured out how to work with it.
A lot of alcohol.
Also setting the rotation mode to Local can help a lot. It allows grabbing multiple bones and posing them all at once, with the Local rotation allowing them to sweep into smooth curves.
But really, the alcohol is going to do the heavy lifting.
