Welcome to Your Weather - RPG Maker MZ (Plugin Pack)

Credit where it started

This pack exists because of Chimaki (conviction-srpg.itch.io). Chimaki's lighting work for RPG Maker MZ — the idea of treating the screen as layered, region-aware atmosphere that reacts to where the player is standing — was the inspiration and the foundational idea behind everything here. Weather Maker MZ takes that lighting concept and branches it into weather and natural phenomena: the same layered, crossfading, region-driven approach, applied to rain, snow, storms, fog, dust, fire, and the stranger things a fantasy sky can do. If you like this pack, go look at Chimaki's work; it came first.

Living weather that changes as your player walks

Paint a region on your map, and the sky changes when the player crosses it. Storm clouds roll in over the moor, fog swallows the swamp path, and snow starts the moment they climb above the treeline — all crossfading smoothly, with the sound design following along.

Weather Maker MZ replaces RPG Maker MZ's built-in rain/storm/snow with a layered overlay engine, a preset editor, and a browser-based sound generator so you can build a complete weather system without hunting for a single image or audio file.

What's in the box

WeatherOverlay.js — the engine

• 48 weather types: drizzle, monsoon, thunderstorm, blizzard, diamond dust, sandstorm, tornado, volcanic ash, fireflies, aurora, meteor shower, eclipse, and more
• Region-based triggers: weather changes as the player walks between painted regions, per-map or globally
• True crossfades between any two weather types, with matching BGS crossfades
• Three-layer rendering: tint + scrolling fog, depth-sorted particles with parallax, and a sprite layer for lightning bolts and the procedural tornado funnel
• Lightning with double flicker, fog flash, screen shake, and distance-timed thunder
• Wind gusts, particle depth, and map-scroll parallax so the weather feels like part of the world
• Weather carries into battle
• Every preset is procedural — zero image assets needed (optional tornado picture supported)
• Custom presets in one line: WeatherOverlay.register("acidrain", { base: "rain", color: ... })
• Plugin commands, script calls, and the vanilla Set Weather Effect command all work

WeatherStudio.js — the preset editor

• Tune any preset's particles, colors, fog, wind, and sound from an in-project editor instead of editing code
• Assign the BGS loops and thunder SE you export from TEMPEST directly to a preset's Sound section

TEMPEST.html — the sound forge

• 28 procedural sound sources across six families: Rain, Wind, Water, Fire, Ambience, and Thunder SE
• Every sound is synthesized from pure DSP — no samples, no recordings, nothing to license
• Six shaping sliders per source (level, body, gusts, brightness, detail, stereo width) and a "new variation" button for endless takes
• Exports seamless, loop-tagged .ogg BGS beds at 6/10/16/24 seconds, one-shot .ogg SE, and .wav
• Runs in any modern browser, fully offline

Built for real projects

• Works with VisuStella Core Engine and Events & Movement Core (aliased, never overwritten)
• Detects VisuStella Weather Effects and steps aside automatically if you use both
• Fully saved with the game: weather, fades, wind, and locks survive save/load
• Indoor maps via <No Weather>; cutscene control via Lock Weather
• Particle cap and scale parameters for mobile and high-resolution projects
• Ships with a full PDF manual, quick-start guide, and a demo map

Compatibility

RPG Maker MZ (all versions). TEMPEST's exported audio also works in RPG Maker MV projects, but the plugins are MZ-only.

License

Use in any number of commercial and non-commercial RPG Maker projects. Do not redistribute or resell the plugins or the sound forge themselves. Sounds you export from TEMPEST are yours to use freely, including in projects that don't use the plugins.
