FAQ
Is Voxelier free?
Yes. Voxelier is free, with no account and no ads: download it from the home page and start building. If you enjoy it, you can support the project.
Can I try it without installing anything?
Yes. The web demo runs the editor right in your browser (recent Chrome or Edge). The desktop version adds the full feature set and performance.
Which Minecraft versions are supported?
Java Edition 1.19 to 1.21.11, and 26.1+. Pick the version in the export dialog and Voxelier writes a world in the matching format. See Export.
I use WorldPainter. Can I bring my projects over?
Yes. Voxelier opens .world files and converts them into a new project at
their original size, with terrains, ground covers, schematic layers and 3D
objects, annotations and biomes. See
Import.
How do I turn a real-world heightmap into a Minecraft map?
Import a grayscale heightmap (.png or .tif, read in 16-bit) and choose its
altitude range: the relief shows up in 3D right away. Add a colormap to paint
materials from an image, refine with sculpting, erosion and rivers, then
export. See Import. Step by step: real-world map guide.
Can I use blocks from mods?
Yes. Import a mod JAR, such as Conquest Reforged, and its blocks become available with their textures and name autocompletion. Stack resource packs to see the map exactly as in game. See Import.
Can I use my schematics and 3D models?
Yes. Voxelier reads WorldEdit (.schem), Litematica (.litematic) and Axiom
(.bp) schematics, and voxelizes 3D models (.obj, .glb) and images. They
all go into a library: place objects one by one, or paint whole zones with
them, like a forest. See Import.
How big can a map be?
Up to 65,536 × 65,536 blocks, though around 16k × 16k is recommended, depending on your machine. The map is rendered on the GPU and streamed tile by tile, so RAM stays low and steady however big it gets. An 8,192 × 8,192 map exports in under 20 seconds.
How do I play my map or put it on a server?
The export writes a standard Minecraft world folder: put it in your saves
folder to play in single player, or upload it to your server. Outside the
painted area, choose what the game generates: void, vanilla terrain or an
endless ocean.
Can I generate terrain procedurally?
The node editor builds terrain from a visual graph with a live 3D preview: combine zones, noise and math, then paint layers, set heights or pour water. For full control, the scripting API also reads and writes the whole map.
Can I walk around my map before exporting?
Yes. Switch to the first-person camera and explore your terrain at player height, directly in the editor.
What hardware do I need?
A Windows or Linux (x86_64) PC with a graphics card supporting Vulkan or DirectX 12. Voxelier adapts its video memory use to your GPU, and a dedicated GPU gives the smoothest 3D view on large maps. See Installation.
Which platforms and languages?
Windows and Linux, with the interface in English, French, German and Spanish. macOS is on the roadmap.
How do updates work?
At launch, Voxelier checks for a new version and installs it in one click. Every update is verified (SHA-256 and signature) before it replaces the executable.
Does Voxelier collect data?
Only anonymous statistics: version, OS, language and crash reports, which help fix bugs quickly. Your projects are never sent, and you can turn statistics off in the preferences.
Where can I get help or suggest a feature?
On the Discord: ask questions, share your maps and suggest the next features.
