This is a personal must have mod.
It tunes down all emotional facial expressions.
Coming from TS2, I just could not get attached to my Sims as long as they were grinning from one ear to the other all day long. I just couldn't take them serious and enjoy my realistic gameplay before I started to use this mod.
Required Packs: -
Compatiblity: Will conflict with any mod that alters these tuning files:
Animation State Machine: Facial Overlays
