Let's consider the old cloth room.  We have had that for the last 23 years.  How many cloth items were made in the first 10 years?  How many experts picked up Poser 5 and made instant clothing items that were WOW?  This has only been out in the wild for 3 or 4 days now.  The Dev Team seems to be able to make it work fairy well, and I have picked up how it is supposed to work mostly because I realize it is not anything like the old cloth room.  You can use the old cloth items but they are going to need to be given new parameters to work.  And finding those parameters is going to take some experimenting. 

Poser 5, 6, 7, 8, Poser Pro 9 (2012), 10 (2014), 11, 12, 13, 14
