There was something available in the Renderosity store for this called Col's M4K4 Mixer, it had a lot of positive reviews so I Was planning to buy it. I try to buy good items before they become unavailable... apparently the vendor removed it so now I can't even find another solution for turning K4 or M4 into older teens, around 12 or 16ish body types is what I'm aiming for. I figured I'd come here to see if anyone knew of another product somewhere on the market or elsewhere that has the ability to turn Michael 4 into a teen or child someway where I can apply muscular features to it, kind of like there is a product on the market for turning V4 into a Preteen, but there is nothing like that for K4 or M4. It's easier to turn Victoria 4 into a teen even without the Preteen product, I've done it lots of times because her body is way more versatile than Michael's, meaning all you really have to do is flatten the breast a little, shorten her height, etc and you can easily turn V4 into a preteen...Seems like Genesis has a whole lot of ways of turning their adults into any age, if I understood it better I'd just switch. But I prefer Poser over Daz.
