Cold Desert Nights Mod gives you full control over biome temperatures and weather behavior, allowing you to customize day-night temperature differences, seasonal shifts, and climate patterns across the world.

Cold Desert Nights Mod Features

The Cold Desert Nights Mod expands RimWorld’s environmental systems by making temperature and weather fully configurable on a per-biome basis.

Biome temperature customization

Each biome can be individually configured with:

  • Day-night temperature difference: Set how much temperatures rise and fall between day and night.
  • Temperature offset: Adjust the overall warmth or coldness of a biome.
  • Seasonal variation: Control how much temperatures fluctuate across seasons, influenced by distance from the equator.

Temperature curve control

You can modify how temperatures change throughout the day using different curve types:

  • Vanilla.
  • Flatter.
  • Flattest.

These affect how quickly temperatures rise after sunrise and fall after sunset.

Advanced weather configuration

The Cold Desert Nights Mod allows detailed control over weather systems:

  • Weather weighting: Adjust how frequently specific weather types occur.
  • Repeat rules: Control whether weather types can repeat consecutively.
  • Early-game restrictions: Prevent certain weather events (like thunderstorms) during early gameplay.
  • Rain behavior: Control whether multiple rainy weather types can occur in sequence.
  • Temperature thresholds: Define minimum and maximum temperatures for weather selection.
  • Event effects: Adjust temperature changes caused by heat waves and cold snaps.

Real-time configuration

All settings can be adjusted during gameplay:

  • Temperature changes apply quickly after updates.
  • Weather changes take effect the next time new weather is generated.

Highly customizable climates

With the Cold Desert Nights Mod, you can create extreme environments such as freezing deserts, mild tundras, or highly volatile climates tailored to your playstyle.

Compatibility notes

The Cold Desert Nights Mod modifies core temperature and weather systems, including:

  • GenTemperature.OffsetFromSunCycle.

  • GameConditionManager.AggregateTemperatureOffset.

While conflicts are not expected, mods that alter these same systems may cause incompatibilities.
