Particle Rain Config Guide: Weather Toggles, Water Tint, Biome Borders, and Spawn Limits

guide

Particle Rain is configured entirely through its in-game interface and hotkeys, and this guide covers the compatibility and weather-related settings that change how precipitation behaves.

Vanilla Weather Toggles

The Compatibility Options group holds the switches that decide whether the original game's weather visuals still appear alongside the mod's particles.

Render default weather — keeps the standard scrolling rain and snow textures visible. Turn it off if you only want the mod's own effects.
Do default splashing — keeps the vanilla splash particles that appear when droplets hit a surface.

Both are simple on-or-off choices. If the mod's effects look doubled up with the base game's, these are the two settings to check first.

Water Tinting

Tint water particles with biome colors applies color drawn from the surrounding biome to rain, streaks, drops, and splashes. With it enabled, precipitation picks up the local palette instead of staying neutral.

Two related settings refine the result:

Water sky color contribution — sets how much the tinted particles mirror the sky's color rather than the water's color. A higher contribution pushes the look toward the sky tone.
Don't tint rain when shaders are enabled — a compatibility switch for shader users. The description notes it should be disabled if Particle Rain is stopping players from joining your LAN server.

Biome Borders and Heightmap Temperature

Two options govern how particles behave at climate boundaries and across elevation.

Cross climate borders — when on, particles are allowed to drift into biomes whose temperature differs from where they spawned. With it off, they stay within the climate they started in.
Use heightmap temperature — stops snow from falling in places that should be getting rain, specifically in biomes where conditions change with altitude, such as the Windswept Hills.

These two work on different axes: one handles horizontal movement between climates, the other handles vertical variation within a single biome.

Spawn Height Limits

Limit spawn height — prevents weather particles from appearing above cloud level.
Spawn height limit — the altitude treated as "above the clouds." Setting this to zero makes the mod read the cloud height from the current world instead of using a fixed number.

Use the limit when you want precipitation confined to the space below the clouds, and leave the value at zero if you would rather it follow whatever cloud height the world uses.

Other Compatibility Notes

Blocks weather ignores — any block added here lets weather spawn underneath it and fall through it rather than being blocked. Entries can come from vanilla or from other mods, and each is identified by the string used in commands and translations.

Performance Pointers

The Performance Options section controls particle volume. Lowering these values cuts the number of particles on screen, which speeds up the game but leaves the effects looking sparser. Maximum particle amount caps how many can exist at once — no new ones spawn past that count. Separate density settings govern normal weather and thunderstorms, each controlling how many new particles appear per tick. Sky particle render distance and Surface particle render distance set how far away, in blocks, sky particles and surface-spawned particles remain visible.

Adjusting these is the main lever if the effects cost too much performance; the compatibility toggles above are the main lever if the effects conflict with vanilla visuals or shaders.
