I think you can use clothing in it. The newsletter says you get the V3 ultra catsuit free if you buy it. (Of course, I already bought the catsuit, so that doesn't do me any good.) It sort of implies you can use it on the catsuit.

I am thinking of buying it. With the introductory discount and the PC discount, it won't be too bad. I would like to be able to change all skin colors at once, as this allows you to do. If you're changing skin tones on the Millennium figures, there are a lot of things to change. Head, scalp, hands, neck, etc. It's kind of a pain to get the colors matched sometimes. This would allow you to change everything with one click.

And of course, there's DAZ's 30-day money-back guarantee. If I don't like it, I can always get my money back. OTOH, it is a DAZ original. It will likely go on sale in the future, for less than it costs now. Possibly when I have vouchers to spare. Do I really need it now? Decisions...
