Blockhammer vs VoxEdit

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, precise position and size controls, reversible effects, and undo. Painting works on block faces at sixteen times the blocks’ resolution and supports text, images, glass, metal, and glowing paint. Blockhammer imports and exports MagicaVoxel .vox files, and exports .glb, .obj, Minecraft .schem, and image or animation formats. Export destinations named by the maker include Unity, Unreal, Godot, Blender, Minecraft, and Teardown. The maker reports rendering a 113-million-block scene and testing scenes beyond one billion blocks. The editor autosaves every minute and can recover work after a crash. Scenes and files remain on the user's machine, and no account is 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 uses the image API configured with the user's own key. The software is in active development, so features may change.
