MadManMike, I really hate to poop on an already frustrating parade, but you mentioned that you bought the Gen3 Iconic Shapes so that you can use all your old content with Genesis. Unfortunately, at this time Genesis won’t autofit Generation 3 clothing and content. That being said, I believe SickleYield has a product that might help with conversion of Gen3 clothing. Here is a link to the product: http://www.daz3d.com/sickle-rigging-and-morphing-system but I would recommend going to the related product thread and asking if it works for Gen3 clothes before you spend the money. Here is a link to the discussion thread: http://www.daz3d.com/forums/viewthread/15492/
Hopefully, I just misunderstood your intentions and haven’t spoiled your anticipated fun.
