Rezcraft

About

Minecraft is Mojang Studios' sandbox building game, publicly released as an early access title in 2009 and formally released in November 2011, later ported to numerous platforms. Rezcraft is a voxel sandbox engine written in Rust with wgpu, inspired by Minecraft, supporting both native platforms and WebAssembly. It includes parallelized world and mesh generation with greedy meshing, colored lighting, and a savegame system on native builds.

How it differs from the original

Rezcraft lets players edit block textures, properties (transparency, solidity, light sources), and definitions directly at runtime via YAML files, and its save system is only available on native builds, not the web/WASM version.

Getting started

You can play the web version directly in a browser with no installation, or download a precompiled native binary that bundles all assets; building from source requires Rust and cargo, with optional feature flags for portable asset-baking, the save system, and extra parallelism.

Known issues & limitations

• platform: Save system does not work with WASM (web version).

Status & roadmap

• The project's readme lists possible future plans including improved world generation, physics, and multiplayer, though none of these are implemented yet.
