Voxel modeler + scene builder

Build voxel models. Compose complete worlds.

Sculpt reusable models, place and group them into freely arranged scenes, light them with real-time ray casting or path tracing, and save or export the world. It all happens in your browser.

Model to world

Sculpt once. Build whole scenes.

VoxiGen has two connected contexts: create reusable voxel models, then compose them into freely arranged, lit worlds without duplicating their geometry.

Create reusable models.

Sculpt, generate, import, layer, and materialize each asset in the Model context. Save it to your library and update every shared placement from one source.

Compose a real scene.

Place models freely, then move, rotate, clone, group, hide, name, and organize them in the Outliner. Ray Cast and Path Trace light the assembled world in the same viewport.

Save the world or ship the level.

Reopen the complete scene as a native VXS file, or export a game-ready level with one GLB per reused module and a placement manifest.

Everything you need

One editor. Model, compose, render, ship.

Create reusable voxel models and complete scenes, work at billion-voxel scale, generate assets with AI, tune materials, inspect scientific volumes, render final shots, and export to the tools already in your pipeline.

Massive scale

Work at billion-voxel scale.

Every model canvas can address 1024 × 1024 × 1024 voxels. VoxiGen streams active regions as you work, keeping detailed models and large volume datasets practical in the browser.

Build detailed voxel models and inspect full-resolution scans.
Reuse finished models throughout composed scenes.
Get the full 1024³ canvas limit on the Free plan.

AI Generations & Agent Builder

Generate assets. Build voxels live.

Use AI Generations to create reference images, 3D models, and voxel-ready assets in one tray, then import or download them. Open Agent Builder to describe a structure and watch editable voxels build live on the canvas.

Choose voxel, detailed voxel, realistic, stylized, or custom style presets before generation.
Tune guidance, seed, and polycount; save or open bundles; import or drag images and 3D into the editor.
Agent Builder: describe a structure and watch it build live on the canvas with editable voxels.

Live final rendering

Raycast and path tracing while you edit.

Use fast raycast mode for clean live lighting, then switch to path tracing for beauty shots. The important part: the render is still the editor view, so you can adjust voxels, materials, sun, threshold, and clips while seeing the final look.

Save screenshots and render stills directly from the viewport.
Raycast view gives a sharp real-time final-look preview for everyday work.
Path tracing converges for higher-quality shots when you want polished output.

Physical materials

Materials, sun, and density are first-class controls.

Palette slots are full material slots, not just colors. Pick from matte, plastic, metal, chrome, glow, glass, frosted, cloud, and tissue presets, then tune roughness, metalness, emission, IOR, and density against a physical sun.

Use roughness, metalness, and emission channels for real surface response.
Glass, cloud, and tissue modes add transmission, volume density, and subsurface-style rendering.
Sun azimuth, elevation, exposure, fog, ground, and environment controls shape the scene lighting.

Scientific volume import

Open NRRD data and dissect it live.

Import NRRD scientific volumes such as CT scans, convert tissue bands into editable layers, and inspect the data with threshold, density, slice preview, smooth interpolation, and cross-section controls.

Open raw or gzip .nrrd files directly in the browser.
Separate tissue bands into layers so scan data becomes editable voxel structure.
Move density and surface thresholds in real time to reveal skin, tissue, bone, or internal detail.

Pipeline export

Export to the tools already in your workflow.

Save models as native VXB or VOX, complete worlds as self-contained VXS scenes, or use Pro mesh and level export for game engines, printing, and web delivery.

VXB preserves one VoxiGen model; VXS preserves the complete scene and its model library.
VOX keeps compatibility with common voxel editors.
glTF, GLB, OBJ, and STL cover web, Blender, Maya, game engines, and 3D printing workflows.

One voxel engine

Build complete worlds. Explore volumetric data.

The same browser GPU core powers reusable voxel models, composed scenes, AI creation, CT/NRRD inspection, and final rendering. Start with a model, scene, or scan, and keep the entire workflow in one editor.

Create workflow

Build reusable models. Compose complete worlds.

Use AI generation, brushes, layers, symmetry, materials, and live final rendering on canvases up to 1024³, then export into the tools already in your pipeline.

Sculpt, generate, import, layer, and materialize reusable models in the project library
Place, move, rotate, clone, name, hide, and group models into complete scenes with the Outliner
Edit one shared model to update every placement, then light the world with Ray Cast or Path Trace
Save VXB models and VXS scenes; use Pro for mesh export or GLB modules plus level.json

Visualize workflow

Open scientific volumes and turn density into structure.

Import NRRD data such as CT scans, move density thresholds and clips in real time, split tissue bands into layers, then edit or export what you discover.

Open raw or gzip NRRD volumes directly in the browser
Use density, threshold, slice preview, and cross-section controls live
Convert tissue bands and scan regions into editable voxel layers
Render, share, or export the result from the same browser project

Pricing

Free is the whole engine. Pro is how you ship it.

Pro unlocks the parts built for shipping real work, including mesh export, level export, and private cloud storage. The engine itself is never behind a paywall.
