The thing that I  found a pain. I use to save copies of v4 that I had twiddled the dials on and set up new materials to create different characters that I used alot. It saved having to go to the pose and material rooms all the time. Now however if I try to save a character no-matter what I call it, it saves in the folder as Victoria 4, meaning that if I try to save another one it would overwrite it. Also if I try to use the full body morph dial on a V4 figure other than the one in the Daz folder it does not apply all the morphs. It means that I will have to save each figure in a pz3 file.
In a way I can understand why they did it, to stop people passing on figures that are really V4, but it's a pain in the ar*e if you just want to save time loading up your regularly used characters.
On the plus side its good to have a Mimic compatible V4.
