Vox works as a voxel editor inside Blender, and each voxel can be swapped for a tile. It adds three tools to edit mode: add voxels, paint voxels, and remove voxels. The add mode covers a default option for drawing a voxel or rectangle and a draw-and-extrude option, while painting offers a brush mode that draws color or a tile set inside a sphere of a given radius, plus a per-voxel mode, with strength, falloff and spacing controls.
Through the Vox panel you define whether an object belongs to a tile set or uses tile sets to build a larger model. Each tile is one object at 1x1x1, centered in the middle. Placement rules cover the layer above, the same layer, and the layer below, alongside custom weight, random probability, and an allow-rotation option. Using tile sets, you can build houses and cities in different shapes and variations and apply colors and geometry nodes effects.
Vox comes in Lite, Full, and Full+Demo editions, and you can start with Lite and switch to Full later. It was updated for Blender 4.2 and 4.3.
