Unobtrusive Weather
This resource pack dramatically changes the appearance of precipitation in Minecraft by making raindrops and snowflakes significantly smaller - they're reduced to just 1x1 pixels in size. This approach greatly improves visibility during bad weather, which is particularly useful for exploration or combat situations.
For streamers and content creators, there's an additional benefit - compact rain and snow particles create less strain on video codecs, which can improve streaming quality and reduce bitrate requirements.
Compatibility
The pack works correctly with the popular Particle Rain mod.
