Hex World Builder

Hex World Builder is a powerful Unity Editor tool that allows you to generate stunning hex-based worlds instantly. Whether you're creating a turn-based RPG, strategy game, or exploration map, this asset lets you bring your vision to life.

⚡ Save time – skip weeks of level design and tile placement.

🧩 Customizable and extendable – add your own biomes, tiles, and clustes.

🎨 Supports both 2D sprites and 3D prefabs – works out of the box.

The asset was developed and published using Unity 6, but it is fully compatible with Unity 2021.3 and newer. It uses standard Unity Editor APIs and does not rely on Unity 6-specific features, ensuring broad compatibility across LTS versions.

🏞 Features

• One-click world generation directly inside the Unity Editor.
• 5 included biomes: Grassland, Wasteland, Desert, Frostland, and Water.
• Easily extendable with your own terrain types and clusters.
• Procedural generation based on Perlin Noise algorithms.
• Smart edge water placement and optional water depth visualization.
• Prefab cluster support – spawn grouped tiles as predesigned structures.
• Randomized terrain tile selection for visual variation.
• Includes 2D biome tiles, but also supports 3D prefabs.
• Clean tile placement with no overlaps and fallback safety.
• Fully customizable grid size, tile spacing, and noise parameters.
