Ryko's Map Generator

Ryko's Map Generator is a fun, easy to use tool that lets you build fantasy world maps in real time. Whether you're a game developer, a writer, or just someone who likes making maps, you can dial in a landmass you like and export it in seconds.

🗺️ Core Features

• 🏔️ Elevation Generation, terrain generated live using layered noise, with natural looking coastlines and a bold, stylized "toon" look
• 🌦️ Climate Simulation, moisture and temperature are calculated behind the scenes so deserts, forests, and snowy peaks end up in the right places
• 🎨 Biome Coloring, oceans, land, forests, and mountains are colored automatically, and every color can be changed with a simple color picker
• 🖌️ Three Visual Styles, choose between Real World, Sketch, and Medieval looks, each with its own set of controls
• 🎲 Seeds and Reproducibility, type in a seed number to recreate the exact same map anytime you want

🎚️ Parameter Controls

• Elevation: scale, detail, persistence, lacunarity, warp strength, sea level, smoothing
• Climate: moisture scale and detail, equator and pole temperature, altitude cooling
• Biome: mountain height threshold, plus line style controls for the Sketch and Medieval looks

Every slider updates the map instantly, so you always see your changes as you make them.

📦 Export

When you're happy with a map, you can export:

• 🖼️ Color map, the finished, colored map as a PNG
• ⛰️ Heightmap, a grayscale image showing elevation
• 📝 Settings file, a text file with the seed and every setting used, so you can recreate or tweak the map later

Everything gets saved into its own timestamped folder next to the app, so you'll never accidentally overwrite an older export.

💻 Getting Started

• ✅ Runs on Windows and Linux as its own standalone app
• ✅ No installation, setup, or account needed
• ✅ Works fully offline, nothing is ever sent anywhere
• ✅ Updates the map live as you move sliders or change the seed

👋 Who It's For

• 🎮 Game developers who want a quick overworld map or placeholder terrain
• 📖 Writers and game masters who want a visual reference for their world or campaign
• 🧭 Anyone who enjoys making maps and wants a fast, easy way to do it without drawing by hand

• 🌊 Rivers & Erosion, more natural coastlines and river networks carved into the terrain
• 🧩 More Biome Control, finer thresholds and custom biome rules beyond elevation and moisture
• 🖼️ More Visual Styles, additional map looks beyond Real World, Sketch, and Medieval
• 📚 Batch Generation, export multiple seeds and presets in one go
• 🍎 macOS Support, a native build alongside the current Windows and Linux versions
• 🎮 Engine-Ready Exports, heightmap and biome formats tailored for Unity, Unreal, and Godot
