- Futa gender
“Gender” doesn’t exist to the game, technically speaking, other than what you write in your character’s profile. You could write attack helicopter in there if you really wanted. Gender in the character model is just setting a bunch of sliders, so you could have a female face with a very masculine jaw, a man with boobs, a woman’s head on a man’s body, etc.
Genitals haven’t been added yet. They aren’t personally very high priority to me, but this is an open source game. Anyone can add anything they want to the game, whether as an official feature (has to be approved by me first), or as a separate version of the game (requires no permission from me). When genitals are added, you likely will be able to choose both, so that’s a yes, but it’s more of a long term thing.
- Breast vore / Unbirth / Cock vore
It depends. Not personally something I’m into, but unbirth is mechanically and graphically similar to standard vore, so that seems reasonable. The others likely require messing around with the character model.
With most fetish-related features, you can answer whether it’ll be added with a few questions:
- Is it vanilla weight gain, lactation, vore, or pregnancy?
- Is it common enough that someone else will add it?
- Will you get someone else to add it?
- Will you add it?
If any of these are yes, it’s probably getting added. If not, I hope you’re ready to learn programming /j.
- How hard is a “numbers system?”
I honestly don’t have a clue what you’re talking about here but I can answer how vore and fat distribution work from a technical perspective.
You have 4 weight-related numbers. Let’s call them fat, standard weight, breast size, and hip size.
Standard weight makes everywhere fatter. Breast size makes breasts fatter. Hip size makes the lower body in general fatter.
Fat is your weight. If you have 0% breast size and 0% hip size, standard weight is equal to your fat. If you have 100% in either breast size or hip size, standard weight is equal to 50% of your fat. If you have 100% in both breast size and hip size, standard weight is always 0. (Though there is one exception: bonus breast size from lactation.)
This basically simulates fat distribution. More boobs means less belly and butt, and more butt means less belly and boobs.
If you’re wondering where vore comes into this… it doesn’t. Vore uses belly fullness which doesn’t have anything to do with fat distribution. Belly fullness is also used by stuffing and pregnancy.
