Voxelizer

Voxelizer: turn any 3D model into voxels, at real-world scale, with its rig and animations intact.

Drop in a GLB, glTF, OBJ or STL. Set how big it really is, pick a voxel size from 1 cm to 1 m, and export to MagicaVoxel, OBJ or an animated GLB. It runs entirely on your PC: no account, no internet, no AI.

Real-world scale, done right

• Type the size you want: 5'9", 1.75 m or 175 cm. Set it by height, width, depth or longest side.
• Fix models made in the wrong units with one click: meters, centimeters, millimeters, inches or feet.
• Voxel size from 1 cm to 1 m, with a slider, an exact value or one-click presets.
• See the result before you commit: "Each voxel is 2 cm, model is 88 voxels tall."

Colors that match the original

• Colors are sampled from the model's textures for every voxel.
• Alpha cut-outs keep leaves, fences and grass see-through instead of solid slabs.
• Optional interior fill makes walls and props solid all the way through.
• Models made of pieces (a car body plus its wheels, a character's head, body and arms) come out whole. Pack files that stack several models are detected, so you can pick just one.

Rigged and animated characters

• The skeleton comes along, and every voxel is bound to its bone.
• Play the model's own animations in the preview.
• Export a .glb with the skeleton and every animation baked in, ready for Unity, Unreal, Godot or Blender.

Export formats

• .vox for MagicaVoxel. Up to 255 colors, picked to fit your model. Models bigger than 256 voxels are split into tiles in a single scene.
• .obj + .mtl + .png: a mesh with a palette texture, so every color is exact.
• .glb: mesh, texture, skeleton and animations.
• .vxc, .json and .ply: voxel-character, raw voxel list and point-cloud formats for custom engines and pipelines.

Touch-up tools

Brush, fill, eyedropper and erase, with mirror painting. Replace one color with another using a tolerance setting, add color variation, reduce the palette, and undo. The preview has ambient occlusion, shadows and adjustable sun and exposure, so you can judge the result before exporting.

Downloads

• Voxelizer-1.0.0-win.zip (recommended): unzip and run Voxelizer.exe. Works with the itch app.
• Voxelizer Setup 1.0.0.exe: a standard installer with a desktop shortcut and an uninstaller.

Good to know

• Windows 10 or 11, 64-bit.
• The first time you run it, Windows may show "Windows protected your PC". Click More info, then Run anyway.
• Very large models at 1 cm can exceed the voxel limit (2 million voxels). Pick a bigger voxel size and it will tell you when it fits.
• Applying an animation made for a different skeleton is experimental. A model's own animations work fully.
