About how big will their various proportions get, at maximum? Is it possible to have, for example, a cowgirl with pretty much all of her weight in her breasts (if rarely), or will weight still be distributed about the entire body in some manner, no matter how skewed her stats are to one particular asset?
First off, I see this is your first post and I'm pretty flattered that it's on my project... So thanks!
Anyways, A cowgirl's stats are relatively balanced in the beginning, only rarely do you find a cowgirl with, say, a slim belly, thin thighs and huge breasts. You can raise a cowgirl without altering her stats without any sort of problem.
Here's a cow I just randomly generated, Daisy: 45/35/20. Whenever she gains weight, 45% of the fat will go to her breasts, 35% will go to her belly and 20% will go to her ass.
If I'm not particularly keen on having a girl that will eventually be shaped like an upside down pyramid, I can feed her modifiers, which are special concoctions that increase one stat and decreases the other two. This can of course lead to skewed stats!
TL;DR: You can go nuts with body types.
Ps, this is Daisy!
I'm starting to feel like this game is a better example of random generation than no man's sky.
