Uhhh... no, there isn't. Nor would there be. The female models aren't procedural models; as in their models are controlled by an algorithm like you'd see in games like Skyrim. These are static models that are rendered into various positions.there any mods for shrinking the ass n tiddies? they're a bit too big for some people
So in order to shrink the ass n tiddies, you'd have to take the 3d models, shrink their proportions down, then render every scene with the new models.
