Step 3: Create a looping sex animation with your fat girl. I reccomend Vinput AutoThruster

This is the tricky part. Often times when we make a large lady in Vam, we are unintentionally constricting the vagina area and the colliders in that region. My advice for having the greatest chance of success is to start with a vanilla character, align your male model in the female's vagina and THEN proceed to start sculpting her slowly and methodically to the size that you prefer. Save often.

This will ensure that you maintain the penetration and any adjustments you make you can verify will not break the animation. It is VERY easy to ruin this type of scene by going crazy with her proportions, so I recommend going slowly and keeping it realistic. Make sure you tweak the glute physics - large butts will absolutely interfere with penetration.

Step 4: Once you are satisfied with your sex loop it's time to get jiggly. Add ExtraAutoGenitals to your female. By default Autogenitals will morph the vagina to simulate penetration, but this is NOT why we are using it - it allows you to trigger ANY morph on penetration. Therefore we will start with the star of our show, her stomach.

I recommend studying up on how a woman's fat belly jiggles when she's getting pounded - there are some obvious and not-so-obvious elements we are trying to replicate. Generally the fat will lag behind the rest of her body as she receives the thrusts. Therefore we want to try and morph the stomach generally up and down with an offset rhythm to the sex animation.

I've found that usually the lower belly fat above the FUPA and around the belly button will flow a little more freely than the upper abdomen fat, so we can replicate this by adding distinct morphs for the upper and lower sections and tweaking the intensity and direction of the morphs to achieve a more realistic effect. Less is more in this situation. You'll get better results using more morphs working together subtly than trying to use one or two morphs swinging dramatically.

Protip: Avoid adding morphs with the red cog (Bone Morphs) to autogenitals. They will destroy your framerate.

Another thing to consider is the tempo of your sex animation... slow and loving, or fast and furious? When the humping is slower, the jiggling will be much less pronounced. When it's hard and intense, she will jiggle like jell-o. Try to match your autogenital morphs with the intensity of the thrusting.

Step 5: Add the Clothskin Plugin

This is optional but I highly encourage it. Using the correct settings, Clothskin can add extra inertia to the female character and amplify/enhance the animated morphs we've just added. It can also easily destroy the carefully crafted jiggling we've created in the last step. The attached image is showing the settings used in the GIFs above.

I recommend dialing in to something very close to the settings pictured and ever so gently tweaking the sliders one at a time until you're happy. Keep the iterations to 1 as increasing them any higher doesn't seem to benefit the illusion in any way.

The three settings that will most affect the jiggle are: Skin Joint Strength, Uniform Sim Strength, and Drag. The higher these are set, the more controlled the jiggle will be, and then obviously the lower they are set, the more intense it will be. You'll have to play around and see what exactly you like most for the scene you are making.

Final Notes:

SAVE OFTEN!!!! It's very easy to break your scene for whatever dumb reason and now you can't get it back to where it was 5 minutes ago. Just keep saving.

Also, try playing with linking your female's abdomen. chest or head with a parent link to your Male's chest or head for extra dynamic movement. Alternatively you can even Lock areas on either character to keep the animation more focused. Sometimes I'll lock the female character's Neck controller in place to stabilize her, and then link her chest to the male Collarbone controller to add extra breast jiggle.

Another way to change up the equation is to have the female character do the thrusting - this can radically change the way the animation plays out. Just keep experimenting!

There are literally infinite possibilities here. That's why I'm going so in depth with this description, to illustrate to you just how much endless fun you can have.

Anyways I hope you have found this informative. Please comment below with any questions you may have! Now get down to pound town soldier!!!
