What is it?

Cubyz is a 3D voxel sandbox game inspired by Minecraft. It uses level of detail rendering to make very far view distances practical, and its chunks are 3D rather than stacked in a fixed height range, so the world has no height or depth limit.

The game features procedural crafting, where tool crafting offers a large space of possible combinations rather than a fixed recipe list. The project is written in Zig, a small systems language, and the codebase was rewritten from an earlier Java version starting in August 2022.

Cubyz runs on Windows and Linux, with macOS unsupported because it lacks OpenGL 4.3. Developers can run a dev build with the provided run scripts or the zig build run command.

Key features

  • 01Level of detail rendering enables far view distances.
  • 023D chunks with no height or depth limit.
  • 03Procedural crafting with a large space of tool combinations.
  • 04Runs on Windows and Linux.

Use cases

  • Exploring a large, procedurally generated voxel world.
  • Studying a voxel engine written in Zig.
  • Contributing gameplay or content additions to an open-source sandbox game.
