Make It Rain! - Rain Where It Never Was Before

This client-side mod dramatically changes the atmosphere in Overworld biomes that never had precipitation. Now in deserts and other arid regions, you can enjoy realistic rain with particles and sound effects.
Compatibility Features
The mod works exclusively within the Overworld, ensuring full compatibility with any addons that add new dimensions. It doesn't interfere with precipitation settings for biomes from other mods, preserving their original behavior.
Since this is a client-side solution, installing it on a server is not required and even not recommended. This means you can use the mod on almost any server without conflicts.
Configuration Settings
For advanced users, a configuration file make-it-rain.json is available. In it, you can change the registryKeyEnable parameter from true to false if you want to allow the mod to override Biome.Precipitation.NONE settings in modded dimensions.
With this change, when the game checks whether to display particles and sounds in a biome, if that biome has no precipitation but is in a dimension with daylight, rain will be displayed.
For playing vanilla Minecraft, this setting makes no sense since the only dimension with daylight is the Overworld.
