====================================================================
As always, use mods and CC at your own discretion. ALWAYS make sure you have the latest/updated versions installed, as well as the necessary packs suggested on the downloads pages – and remove all Mods and Default Replacement items BEFORE installing each official game patch.
====================================================================
Deaderpool – MC Command Center (Story Progression, Dresser options, Ability to control Clubs, World Population, Game Notifications, etc. A MUST have to “fix” things that Maxis hould have!)
Turbodriver – WickedWhims (NSFW/18+) (Sims 4 sex mod, Menstrual Cycles, Exhibitionism, Adds Sim Genitalia, Miscarriages, Abortions, etc. You will also need to download additional sex animations at LoversLab for greater variety of sex positions – free registration required).
MoxieMason – No Mosaic (Removes the mosaic “blur” when Sims undress).
Basemental – Basemental Drugs (NSFW/18+) (Adds Drugs, Alcohol, Bouncers, Addiction, Rehab, Raids, Arrests, etc).
KawaiStacie – Slice Of Life (Adds game buffs, changes Sims appearance – blushing, losing teeth, bruising, acne, adds apps to Sims phone to build skills, etc).
PolarBearSims – Have Some Personality Please! (Enables Sims to act appropriately according to their traits, for example; mean sims will do mean interactions autonomously and more frequently).
DerShayan/NoirSims – Fan Art Maps/Overrides (Default Replacements for World Maps that actually match game/live mode environments).
Scarlet – SimCity Loans (Allows Sims to apply for finance that they have to pay back with interest over installments or get negative moods), and Toddlers and Children Can Die of Anything (self explanatory).
MSQ Sims – Realistic Trees (No Fade) (Stops trees from fading when you zoom close in live/Tab modes).
Buckley – Camera Mod (Enables camera to zoom low to ground in live/Tab modes. There’s an updated version by Szielins which is probably more stable but IMHO doesn’t work as well).
Andrew’s Studio/S4S – Pose Player, and Teleport Any Sim (Use to summon and pose your sims. Thousands of poses can be found on various Sims 4 sites; too many to list. For examples of poses I use see here).
Luumia – Eye Shine Remover, No Glo, and No Blu (Removes the shine from Sims eyes, makes indoor lighting darker, and removes the blue tint and glow on Sims respectively).
LiKo/Kiolometro – Baby With Hidden Crib and Crib Good Night (Default Replacement – Replaces Default Crib to make it appear invisible so can use CC cribs for babies).
Brazenlotus – Toilet Bush Recolours (Texture Overrides of the Anything Goes Party Bush, Duty Calls Citizen Bush, Open Air Toilet, removes the flowers).
Kijiko – Remove EA Lashes (about half way down the page, beneath 3D Lashes v2).
Cepzid/Fian/Ruffian – Brutal Brawler. Replaces fight animation (removes “dust cloud” – but not for children).
Weerbesu – More CAS Columns (self explanatory).
Crosire – ReShade. (Advanced post-processing injector. Enables lighting and visual effects on the game including ambient occlusion, depth of field, lighting and colour correction, and more).
Marty McFly – qUINT. (A selection of shaders that can be used with or independent of ReShade including reflectioms, bloom, colour grading, DOF, ambient occlusion, and more).
