Oh i can?You can literally do that. For a while now. You can change skin/fur/scales color, change their patterns and compositions, add or remove hair, change musculature, with characters like Maya the customization options are near endless, you can make she look like an elf or a vampire, succubus or an office lady, you can make Bol look like an orc, or a mutant, you can make Max look like a goblin, you can change clothing... I've been able to turn Maya into almost 30 different characters, 20 different characters with jenny and a few with alissa and shey. I don't know what else you want from customization options. Just type O and be creative.
Well then. How do i add some wings, add markings i want, add on some headplates and give him a custom dick? I can play with a few sliders, but that's it. Maybe you are afraid of beast characters, but humans look all the same to me. The moment i can recreate a real dragon is when i call it real customization.
