What is it?

Voxel Tools adds volumetric terrain to Godot Engine 4 as a C++ module or extension. Unlike heightmap-based terrain, voxel data can represent overhangs, tunnels, and caves, and players can dig or build at runtime.

The voxel data is converted into chunked meshes that are paged in and out, which makes infinite worlds possible. Terrain can be generated procedurally through custom generators or streamed from other sources. Storage uses 8-bit or 16-bit channels for general-purpose data.

Rendering offers two styles: Minecraft-like blocky terrain with multiple materials and baked ambient occlusion, and smooth terrain with level of detail via Transvoxel. An instancing system places foliage, rocks, and other decoration on surfaces, and the module integrates with Godot physics as well as a faster block-based collision option.

Key features

  • 01Realtime terrain editing in-game, supporting overhangs, tunnels, and player-driven digging and building
  • 02Chunked meshes with paging, enabling infinite terrains
  • 03Blocky voxel rendering with multiple materials and baked ambient occlusion
  • 04Smooth terrain with level of detail using Transvoxel
  • 05Instancing system for foliage, rocks, and decoration
  • 06Godot physics integration plus a fast Minecraft-style collision option

Use cases

  • Building voxel-based survival or sandbox games with destructible terrain in Godot
  • Creating large procedurally generated open worlds that stream chunks as the player moves
  • Prototyping Minecraft-like block worlds or smooth organic terrain inside Godot 4

Things to know

  • GDExtension support is still on the roadmap, so the module build is the main supported path.
