We did consider that!
But the current breast animation rig for Woolly is too limited at the moment to make something like that…
Mostly because it would introduce a lot of variations that would need to be accounted for in the boobjob, otherwise it would look weird in the animations.
We do need to remake the boobs eventually, since the current setup would not look correct once we add the missionary pose.
Once we reach that point, we can consider adding some size variations, but no promises at this point.
Regarding lactation, that is something we can do (and was already requested on our discord!), especially after we've finished adding the kind of "action" that would help her produce milk 😏
