Voxel Builder is a voxel-based 3D modeling application for making and converting voxel scenes. It offers terrain, cube, sphere, and isometric generators, along with interactive modeling, symmetric drawing and painting, transforms, and color groups. Rendering options include a Three.js sandbox, GPU path tracer, basic PBR rendering, and post-process effects. It can voxelize 3D models in GLB, OBJ, STL, or PLY formats, as well as images and Unicode or emoji text. Projects can be saved or loaded as JSON and MagicaVoxel VOX files, then exported as GLB, GLTF, OBJ, STL, or PLY. Saving tools include local storage, snapshots, quicksave, undo, redo, and ZIP snapshot backups. The project includes a Blender importer script, and baked GLB meshes can be used with Blender and other 3D software. Voxel Builder is free, GPL-3.0 licensed, and described as usable online or offline. Browser support covers desktop and mobile; Electron downloads are listed for Linux x64 and Windows x64.
Who it is for
It suits people creating voxel art who want generators, painting tools, and model conversion in one application. The project recommends a tablet with a pen or a Wacom tablet for the best experience.
What is good
- Generators cover terrain, cubes, spheres, and isometric forms.
- Voxelizes models, images, and Unicode or emoji text.
- Supports multiple import, save, and export formats.
- Includes snapshots, quicksave, undo, and redo.
- Described as ad-free, without trackers or logging.
What to know first
- High voxel volumes can reduce frame rates.
- Browser storage is limited; Electron is recommended for capacity.
- GLB voxelization does not support geometry animations.
- Electron downloads are listed only for Linux x64 and Windows x64.
Verdict
Voxel Builder combines voxel modeling, rendering, and conversion with a range of save and export options. Be mindful of performance and browser storage limits when working on dense or large projects.
