Sims 4 Kastemel Feedism Mod REDUX

I AM NOT A SIMS MODDER, I JUST LIKE TINKERING WITH STUFF.

MOD ORIGINALLY MADE BY “KASTEMEL”.

THERE MAY BE UNFORESEEN BUGS.

CREDITS:

“Kastemel” - Made the original mod

@zel1302 - Made stuffing belly sliders

@daftidiot1 - Reworked the old mod to successfully load into the game

@mrmoto - XML editing

Saw this mod in an old Sims 4 Discord server that disappeared one day. Made by the user “Kastemel”. Was bummed out that it didn’t work cause it looked like it was really feature rich and it has been abandoned for a few years. As there was nothing else quite like it, I decided to take up the task of bringing it back to life. There were also some belly/stuffing sliders made by @zel1302 in that discord that I managed to recover before it all vanished. I incorporated that into the mod as well.

With the help of @daftidiot1, and a lot of hard work, I managed to restore most of the mod’s old features.

Requirements:
XML Injector
Lot51Core
This mod overwrites the seating_sit interaction tuning

Features:

Stuffing
Stuffing commodity: fills and applies buffs when sims eat while hunger is full. Contains failure states
Intestinal Fortitude Commodity: decreases as sim overeats and spends time stuffed, contains failure state
Appetite Skill (minor): Build skill by spending time stuffed. Higher skill level lets sims stuff longer without hitting limit, decreases odds of getting sick, and makes sims get hungry faster.

Buffs:
Stuffed (vampire: Glutted)
Overstuffed (vampire: Plasma Pumped)
About to Burst (vampire: Sanguinous Sloshing)
Gonna Blow! (vampire: Gonna pop!)
Danger Zone (nauseated)
Indigestion (uncomfortable)
Bloat Brained (vampire only, dazed)
Jostled (stuffed woohoo)
Lost Lunch (after throwing up due to stuffing) (vampire: Plasma Purge)

Interactions:
Deep Breaths relieves stuffing and nausea
Pass out in chair food coma (you have to be sitting down already when selecting interaction)
Overeating Death
Stuffed and Overstuffed Idle Mixers

Object States:
Foodbaby states: Integrated Zel1302’s overstuffing mod. A new belly slider for this replaces the negative range of muscle. You may see other sims with big stomachs, you can set their physique to 0 via MCCC if you wish. Doesn’t work well on muscular sims as the new belly function slides toward zero over time to simulate “digestion”. Not perfectly implemented, but it’s the best I can do right now.

Weight Gain
Heavyweight (fatness 60+) sims get tired from standing for long periods and need to sit or lay down to recover. Sims with higher fitness gain fatigue more slowly.
Heavyweight sims have a random chance to weaken dining and living chairs they sit on. Sims of 80+ fatness have a 5% chance to break a chair by sitting in it when it is fully weakened.
(Added cheat menu option to make any chair unbreakable)
Heavyweight sims have the Slow walkstyle imposed on them. They overheat faster, but get cold and freeze slower. They get tired and hungry slightly faster and gain the Appetite skill more quickly.
Lightweight sims (-60 fatness and under) get hot less quickly but get cold more quickly. They gain the appetite skill more slowly and experience dazed emotions more intensely
Hidden buff for recent weight gain
Tight Clothes Commodity: Progressing upwards (or downwards) through the visible fatness states (intervals of 40) increases clothing tightness. The commodity can be reset through the order category on the computer, the shopping category on the phone, or the cheat menu by clicking on the sim.
Level -2: applies the Loose Clothes buff.
Level 1: certain outfit categories will apply the Bursting at the Seams buff. Others will apply the Comfy Clothes buff.
Bursting at the Seams grants the social interaction Does this Outfit Make Me Look Fat?
Level 2. Applies the Too Tight buff. When moving or sitting down, Sims have a random chance of having the Wardrobe Malfunction buff applied. Their shirt or pants may rip revealing their body. If a feedee is at home and rips clothing, they get a flirty buff.
Level 3. Applies the Nothing Fits! Buff. Sim will be naked or close to naked (depending on what other mods you have). Cannot wear anything until they buy new clothes, or you reset their clothes via cheat menu.
Using potions or cheating weight changes doesn’t seem to influence this system. You have to change weight in-game the regular way, by eating or exercising.
Sims over a certain size have a chance of overflowing the bath tub when taking a bath.
