Genesis has a belly button depth slider.
Genesis has a lot of sliders & mix morphs.
There's a lot you can do with just the sliders & mix morphs.
Even if sliders & mix morphs are not enough ,Genesis has zBrush.
There are no limits.
Zev0's A3 might not be the 100% orginal A3 but she looks good ,does she not ?
