You can't directly turn off weather deaths in The Sims 4. However, you can control the severity of weather events and how they affect your Sims using various methods:
1. Using Cheats:
- "testingcheats true" enables cheat mode.
- "weather.set_weather_type [weather type]" sets the weather to your desired type.
- Example: "weather.set_weather_type Sunny"
- "weather.set_weather_severity [severity level]" controls the intensity of the weather.
- Example: "weather.set_weather_severity 0" sets the severity to the lowest level.
2. Modifying Game Settings:
- Change the world's climate: Select a world with a milder climate or one that doesn't experience extreme weather events.
- Disable specific weather events: Some worlds offer options to disable specific weather events like thunderstorms or snowstorms.
3. Using Mods:
- "Weather Control" mod: Allows you to customize weather conditions and disable specific weather events, including those that cause death.
Remember to always back up your save files before using cheats or mods.
