Blockhammer review
A broad, free voxel editor for building, painting, lighting, and exporting scenes.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Blockhammer is a free desktop voxel editor for building, painting, lighting, and exporting cubic-block scenes. It is aimed at creators who want scene-focused editing across macOS, Windows, and Linux, with support for layered organization, object transforms, sculpting, materials, references, rendering, and multiple export formats. The application is distributed as a direct download without an account or project server, and is currently described as early access.
Its strongest area is the breadth of scene creation tools. Cubic voxel modeling includes place, erase, box, profile, and sculpt tools, while layers and objects can be named, shown or hidden, locked, and transformed. Non-destructive bevel, hollow, fill, noise, and grain effects add further control. Face painting supports brushes, text, sprites, and material properties. Scene lighting, shadows, skies, render mode, and turntable exports extend the workflow beyond basic block placement. Imports include Blockhammer and MagicaVoxel scenes, reference images, and meshes; exports include glTF, OBJ, MagicaVoxel, and Minecraft schematic formats.
Blockhammer also fits workflows connected to Unity, Unreal, Godot, Blender, Minecraft, and Teardown through its formats and stated integrations. Autosave, undo, crash recovery, mirroring, and copy and paste support iterative scene work. The main constraints are its early-access status and its focus on static voxel editing: animation tools are not included, and an imported MagicaVoxel file with multiple animation frames places only the first frame. Choose Blockhammer if you want a free, cross-platform editor with modeling, painting, lighting, organization, and export capabilities in one desktop application. Look elsewhere if animation editing is central to your workflow.
