All of that was done manually through painstaking detail work. There are no breast simulations or physical interactions going on here. While I will continue doing manual breast physics in Supermodel, I will combine that with systems that simulate physical pressure on them almost automatically. This last part is the most important one for titfucking. I don't want the penis to be inside the breasts; I want the breasts to be soft, pliable, and shape themselves around it.Sounds great. I did enjoy the breast physics in LLTP though. Better than many other games.
