After 2 years of going through hundreds of game assets, I'm finally happy with the state of this project. It fixes seasonal visuals and inconsistencies across the game.

Just want visual fixes? Use only the Assets folder packages. Everything else is optional.

PLEASE READ

1. ASSETS FOLDER (CORE MOD)

Fixes to environment assets:

• Building shells (the fake background buildings) now show snow in winter.
• Trees: many now use the AnimatedTree shader for fluid wind movement. (Many DLC worlds used to the stiffer SimpleTree shader, which resulted in really ugly wind formations).
• Smaller fixes:
  • Missing shell shadows in Ciudad Enamorada.
  • A misplaced bridge in Ravenwood's ghost district.
  • Missing snow on collectible rocks, and dirt piles.
  • Shadow models turning into white blocks in snow.
  • Ivy swaying in windy weather.
  • and MORE things I'm too lazy to name.

2. TUNING FOLDER (optional)

⚠️ Conflicts with other mods that edit world seasonal tuning.

• Fixes Evergreen Harbor and Gibbi Point, where trees kept their leaves until snow suddenly stripped them.
• Enables or adjusts fall colors, falling leaves and snow in worlds that normally don't have them.

3. WORLD FILES (optional)

• For cleaner snow in those worlds, grab the world files HERE. They stop lots from appearing outlined in snow.

4. OPTIONAL TreeMatte|Matte|Cloud Backdrops (work in progress)

Adds seasonal changes to distant 2D scenery: trees, clouds and backdrops. It currently covers Lovestruck, Life & Death (partial) and Adventure Awaits. It's kept separate because other mods edit these assets, and people have their preferences.

5. OPTIONAL Files

Pick whichever you like:

• AutoTurnedOnEmitters: some community lot objects turn on and off automatically with the weather. This covers pond effects (mosquitoes, frogs, turtles), sprinklers, splash pads and bird feeders.
• LessCloudsDuringCloudyWeather: softer cloudy weather that keeps some light and shadow.
• SlowerPuddleEvaporation: rain puddles stay visible longer.
• LightSnowWeatherStopsMelting: restores a removed behavior, so snow doesn't melt during Light Snow.
• TreehouseOverride: the Growing Together treehouse changes in seasons. Trade-off: when Sims go in or out, the curtains don't animate and Sims clip through them.
• GrassRecolors: tones down some overly bright Base Game grass to match the terrain. It's separate because it strays from the original look.
• RedFallTreesConsistentlyRed: red fall trees stay red instead of fading to greenish-brown. Fall should be colorful!
