Rain and Water

Rain and Water (R&W)

Rain and Water makes weather and water look natural instead of blocky. It is a client-side Fabric mod: install it on your own game, no server install needed, and it works in singleplayer and on any server.

Features

• Natural rain — realistic rain streaks with adjustable thickness. Rain now travels along the wind and is blocked by walls, so you get a rain shadow behind buildings. Ring-and-crown splashes where drops land; vanilla rain particles replaced.
• Clearer, realistic water — less blue and more transparent near you, with refraction, depth absorption tinted by biome, fresnel, sun and moon glints, rain ring ripples and soft shore foam.
• Reflections — screen-space reflections on water and puddles: blocks, terrain and bright lights are mirrored, and the sky is used where nothing is hit.
• Wet ground — after about 10 seconds of rain, ground darkens in raindrop dots, soaks through, gets a slight sheen, then dries in patches once the rain stops.
• Puddles — puddles form on open ground, fade at their edges instead of cutting off in straight lines, and evaporate over roughly 4 minutes.
• Wet players, mobs and items — entities darken in patchy blotches and get a wet sheen for about a minute. They drip glassy teardrops for 20–30 seconds after leaving rain or water, and dropped items dim.
• Wakes and ripples — water has a real wave simulation: rings spread, bounce off shores and interfere with each other. Players and mobs leave a trailing wake sized to their body, and things falling in splash by how far they fall.
• Portal Gun support — if the Portal Gun mod is installed, portals glow in water and puddle reflections. Walls hide a portal's mirror image, and nearby light sources reflect too. Nothing to configure.
• Light reflections — the nearest light sources mirror in water, even from off screen (lightReflections option).

Requirements

• Minecraft 26.2
• Fabric Loader 0.19.0 or newer
• Fabric API
• Java 25
• A GPU that can run the vanilla renderer at your usual settings. Reflections and the water shader add per-frame cost, so lower reflectionSteps or turn reflections off on weak hardware.

Configuration

A file is created at config/rainandwater.properties on first launch. Options include reflections, reflectionSteps (default 24), dropsPerColumn (rain thickness, default 9) and wakes. Each option can also be overridden with a -Drainandwater.<option> JVM flag.

Compatibility

Tested alongside a large modpack including ImmediatelyFast, Biomes O' Plenty and Terralith with no errors from R&W. It has not been tested with Iris or shader packs, so treat those as unsupported for now.

Known limits

• Only things on screen can appear in reflections.
• Damp ground shows the sky tint only; full block reflections are on water and puddles.
• Villager robes and armor layers do not get the wet sheen yet.
