"Squishy" is the new "firm." I've been experimenting with ways to make them look more "life-like" for ages -- this is one such experiment. You may recall the other one where she flops them out on the counter-top -- same technique.
What I really want is a 3D modelling program that can take the base models I use and apply "giant breast soft-body deformation" on them. And I'd like this custom software, written by someone other than me, to cost less than $100.
Not gonna happen... so I do each one, at least for now, by hand.
