UPDATE 5/05/25: Sorry I accidentally locked the Patreon post by mistake, it’s fixed and now public!
Yes, I know I'm retired, but I have been meaning to edit that goofy smile for AGES, I just could never find the relevant pose to override...and now I finally have! I figured this might be something others might want and I'm not sure if it's been made yet ( apologies if it has been) so here you are. This replaces the generic thumbnail you see at the bottom of the Sim selection bar in Live Mode, the face on the fullbody pose when viewing Sim profiles (the fullbody adult pose is slightly different but still just a basic standing pose), the portrait in Transfer Sims Between Households on the map screen etc.
If you like these try my other free overrides for UI emotions.
NOTES - Two packages for Teen-Elder: Neutral or Smile. You can only put one in your Mods folder. The other is for Child, which is the subtle smile. - Before and after putting this in, or taking it out of, your mods folder, you must go to Documents > Electronic Arts > The Sims 4 (or equivalent) and delete the localthumbcache.package so that the new thumbnails will generate properly.
If you want to make your own overrides for this portrait pose, go to Sims 4 Studio > Override > The Teen-Elder one is: a_cas_thumbnail_fullbody_female_x. Replace the starting 'a' with 'c' to get the child version, then you can Export them and make your own overrides! i_cas_thumbnail_fullbody_x for Infant, replace 'i' with 'p' for Toddler.
