Okay, a lot of people are confused about what I mean by model. It's basically the base in which the animators use to create different animations. Take adult sims, both male and female. Teen-elder, along with female and male sims, uses the same model so the development team can use the same animations throughout these age/gender groups without any issues. However, if someone were to say, apply these animations to a child sim (which uses a different model) the animations would become messed up. If you've ever seen a child sim stretch unnaturally in you're game, this is why. What I'm advocating for is using the same base model so as to not have to start from scratch.
