Finalising and exporting

Everything about getting a model out lives in the Export section of the Voxel tab. There are four ways out:

Way out	Gives you	Use when
Finalise To Mesh	An ordinary Blender mesh, in the scene	Rendering, sculpting, or your own export settings
Export File	A .glb or .fbx for a chosen engine	Shipping to a game engine
Export .vox	A .vox file	Opening the model in another voxel editor
Export Sprite Sheets	8-direction PNG sheets + metadata	2D games (animated characters)

1. Export File: pick an engine preset.
2. Export .vox: save the model as a .vox file.
3. Atlas, Mesh Cleanup, Texture Files and Send to Unreal (Live Link).

Finalise To Mesh

In the Voxel Mode section. It bakes the model to one mesh carrying its colours and materials.

Option	Meaning
Merge Coplanar Faces	Merge flat runs of faces into big quads. Much lighter, and a quad never crosses from one colour to another.
Keep Voxel Model	Leave the editable model in the scene beside the mesh
One Object Per Group	One mesh per group instead of one mesh
Build Rig	Also build an armature from the groups (see Groups)

Note

A merged mesh has T-junctions: fine for games and rendering, but not watertight. Leave Merge off if you need a manifold mesh for 3D printing or booleans.

Export File: engine presets

Export ▸ Export File, or File ▸ Export ▸ Voxel Model (.glb/.fbx). Pick an engine and a file name:

Engine	Format	Conventions
Godot	glTF binary (.glb)	Godot’s recommended format, Y up
Unity	FBX	−Z forward, Y up, metres
Unreal	FBX	Centimetres, the same settings as the live link
glTF	glTF binary (.glb)	Engine neutral: Three.js, Babylon, Sketchfab, web
FBX	FBX	Engine neutral: Blender’s own axes, −Z forward, Y up, metres

These are presets, not options, on purpose. Every engine disagrees about which way is up and how big a metre is, and getting it wrong doesn’t fail: it gives you a model on its side at a hundredth of the size.

Bake Atlas (on by default) collapses the palette into one material and one texture. An engine pays a draw call per material, so shipping 256 palette materials is not an option. The exported model carries one material, one embedded texture and UVs into it.

Animation is included when the model is a rigged character or has a rig from its groups. The selected Action is exported with its frame stepping. See Characters for what each output mode can export.

Atlas and cleanup settings

Under Export:

Sub-panel	Settings
Atlas	Atlas name, pixels per colour cell, share one atlas across models. Bake Atlas Into Scene does it in place so you can inspect it.
Mesh Cleanup	Dissolve (with angle), merge distance, triangulate
Texture Files	Also write roughness/metal (ORM) and emission maps, output folder and prefix. Unset, textures are packed into the .blend.

Export .vox

Export ▸ Export .vox, or File ▸ Export ▸ Voxels (.vox). This writes the voxels, palette and materials to a .vox file.

• Metallic and emission are saved. The roughness of plain matte colours is not.
• A .vox model can be at most 256 on a side. A bigger grid is saved as several models placed side by side in the file.
• The active model is written, one model per file.
• Rigs, animation and groups have no place in the .vox format and are not written.

Sprite sheets

For an animated character, Export ▸ Export Sprite Sheets ① renders the selected Action from eight directions.

② Frame Size and Camera Angle.

Setting	Choices
Frame Size	64, 128, 256, 512 or 1024 px
Camera Angle	Level (0°): true front/back/side views for side-scrollers. Angled (30°): the classic three-quarter view. High (45°). Top-Down (60°) for top-down games.

It writes a new animation_sprites folder (it never overwrites an old one) holding:

• one sheet per direction,
• every frame as its own transparent PNG,
• a JSON file with frame timing and the pivot point.

Update Every N Frames and Strict Grid carry through, so a sprite sheet can have the stepped, perfectly axis-aligned look of hand-made pixel art.

Send to Unreal (Live Link)

If you use Unreal, Send to Unreal pushes the model straight into an open Unreal project, with no file dialog. It needs the paired Voxel Mode Unreal plugin installed in the project; the plugin watches an exchange folder.

The plugin ships with the add-on. Press Install Unreal Plugin in this panel, pick your Unreal project’s folder (the one with the .uproject file), then restart the Unreal editor. It is copied to the project’s Plugins folder; to update it later, close Unreal and press the button again.

Setting	Meaning
Destination Path	Where in the Content Browser the asset lands
Pivot	Where the asset’s origin goes
Collision	Collision to generate
Send Textures	Include the atlas textures
Animation	Mode, export all Actions, morph targets, bake step, name prefixes for skeletal mesh / skeleton / animation
Options	Asset, material and suffix naming, master material, lightmap UVs, replace existing, exchange folder

Check For Models looks for models waiting to come back from Unreal, and Open Exchange Folder shows the folder the two sides share.
