Primary information

Vox is an add-on for Blender which can be used as a voxel editor or tile map generator.

Example as a voxel editor:

Example as a world generator:

Using tile sets, not only can you build houses in different shapes and variations, but also apply colors and geometry nodes effects. Example tile sets:

3 new tools will be added into edit mode:

Add voxels, Paint voxels and remove voxels.

Add voxels

Modes:

* Default — draw a voxel or a rectangle.

* Draw and extrude — draw a point or a rectangle and extrude at second mouse click

Alt — pick a color from voxel

Ctrl — remove voxels

Draw voxels

Modes:

* Brush — draw color or tile set inside a sphere with given radius

* Per voxel — draw color or tile set of one voxel

Switcher — draw color or change tile set

Strength, falloff and Spacing -similar to regular graphic settings.

Accumulate not yet implemented

Alt — pick a color from voxel

Define is object is in tile set or uses tile sets to build the big model.

Use as voxel

Layer above, Same Layer, Layer Below — define basic rules, where this tile used. For example, if you define Same layer front as «Empty or Other» this tile will be set only if there is no voxel in front of this tile.

To help you identify which button is front, left or right, all changes indicates in 3D-view:

Use custom weight — Tiles with more count of rules have more weight, and tile with maximum weight and passed all rules will be selected. In some cases, you can set custom weight.

Random Probability — If several tiles with same weight can be putted in same spot, they selected randomly. You can add some probability here to make some tile appears more often.

Allow rotation — allow rotating tile in 90 degrees.

Only on the ground level — this tile can be used only if z equals 0

Only on even — this tile can be used only if x y or z coordinate is

Current limitations

Blender 3.1, 3.2, 4.2, 4.3 only!

If scale rotation or transform is not default, Vox is not very accurate, I recommend using applied transform.

To use color in models, Vox uses «Realize Instances». If you have troubles with performance with high poly tiles — consider using switchers:

Simple box — Replaces all models by boxes only in viewport

Simple Instances — Disables Realize Instances — colors is ignored. In viewport in render.

To use color information in tiles, use Attribute Col, not a Vertex color node:

To use a UV map, use Attribute node instead regular UV map nodes:
