What Voxel Mode is

Voxel Mode is a Blender add-on for building with voxels: cubes on a grid, one colour each. It all happens inside Blender. Your voxel models sit in the same scene as your lights, cameras and other meshes, and they can be rigged, animated and exported with the rest of your project.

The one idea worth knowing

A voxel model is a grid, not a mesh. Every voxel model you make is a normal Blender object. The grid (which cells are filled, and with which palette colour) is stored on that object. What you see in the viewport is a set of chunk meshes that Voxel Mode rebuilds from the grid whenever it changes - while you are editing it. A model you are not editing is drawn as one object, so a scene full of models stays light.

That explains several things you will notice:

• You edit in Edit Mode, with Voxel Mode’s own tools. Press Tab on a voxel model and the toolbar shows Attach, Erase, Paint and Select instead of Blender’s mesh tools. Blender’s Extrude or Knife would have nothing to work on, because the model’s own mesh is empty.
• Clicking a model in Object Mode selects the whole model, never one of its chunks.
• Scaling a model resizes its grid in whole voxels. It never stretches the voxels, because a model has one voxel size. See Models and the grid.
• Undo inside a model is Voxel Mode’s own. It records only the voxels that changed, so it is fast even on huge grids. Ctrl + Z works as usual, and covers the current editing session; Blender’s undo in Object Mode holds every step before it.
• To leave the grid, you finalise. Finalise To Mesh bakes the model into an ordinary mesh with its colours and materials, ready to export. You can also bring a finalised mesh back into an editable model.

What is in the box

Area	What you get

Selection	Box select, connected (magic wand), same colour, by group. Grow and shrink. Move, duplicate, rotate, scale, mirror, fill and delete.
Colour	A 256-entry palette where every entry is also a material: roughness, metal, glow, opacity, water and glass. 23 built-in palettes.
Shapes	996 ready-made shapes in 19 categories, plus your own library of saved shapes, shareable as .zip packs.
Generators	33 generators (terrain, trees, rivers, buildings, cities, caves, planets and more) and 33 one-click Scene presets.
Characters	A guided rig for bipeds, quadrupeds and slimes, with 46 editable sample animations.
Conversion	.vox import and export. Voxelize any mesh. Turn a picture into voxels. Read a finalised mesh back into a model.
Export	One-click presets for Godot, Unity, Unreal, glTF and FBX. A live link into Unreal. 8-direction sprite sheets.

A model’s grid can be up to 1024 voxels on each side.
