Blockhammer is a free voxel editor for building scenes from cubic blocks, available for macOS, Windows, and Linux. Its modeling tools include layers, named objects, exact position and size controls, reversible effects, and undo. For surface detail, users can paint block faces at sixteen times the blocks’ resolution with text, images, glass, metal, or glowing paint. It imports and exports MagicaVoxel .vox files and exports .glb, .obj, Minecraft .schem, and image or animation formats. The maker lists Unity, Unreal, Godot, Blender, Minecraft, and Teardown as destinations for exported work. Blockhammer autosaves every minute and can restore work after a crash. Scenes and files remain on the user’s machine, with no account required. Crash reports may include errors, recent activity, and graphics hardware details; reporting can be disabled. Optional AI texture generation is off by default and sends prompts to the image API configured with the user’s own key. The software is under active development, so features may change. Platform requirements include macOS 11 or later, Windows 10 or later on x86_64, and x86_64 Linux with glibc from Ubuntu 22.04 or newer.
Who it is for
Blockhammer suits people creating voxel scenes who want precise object controls, detailed surface painting, and exports for named tools and games. It may also suit users who prefer local files and no account requirement.
