So quick run down of what this does.
Adds new character models. The new character models have a higher poly count so they should look generally better than the base game models. They also have genitalia.
Added variation in butt sizes.
I feel like the variation of breast, muscles, and fat that you see in the base game is pretty narrow, compared to what you see in real life, so I've increased that variation. While people at the upper limit of what I modelled exist, they admittedly may appear in the game more often then in real life and different people may have different experiences. I'm mostly going to attempt to deal with the distribution in my physical attributes mod, because I don't want to have to edit a ton of ethnicity files.
I've corrected for the way the base game coded its head and body animations, so that there isn't a gap between the torso and head like there is in the base game.
I've added bones to the base models that allow animators to move the penis, butt, breasts, vagina, balls, and stomach of the models. In my attempts to create sex animations I basically found that I needed more control of these areas.
I've adjusted the clothing to work with all these changes.
Yes, I've added sex animations too. I just changed the name because the last name was too long and doesn't give the full impression of the things this mod does. If you can't figure out the sex animations stuff there's a bunch of stuff that work immediately.
My Coetus Anima mod includes events coded with each animation.
Included in this mod is a version of the Carnalitas example scene which works with the animation. So if you have Carnalitas, you can see the animation using the sex interaction.
New Clothing and Hairstyles:
The new clothing and hairstyles won't exist in the game by default, but they are available to be added in full screen barbershop
If you want to add any of the underwear to a character you have to make them naked via the toggle in full screen barbershop first. This removes the modifiers added when the vanilla clothing is added.
