Voxel editor basics

The voxel editor is the second half of the app - a full 3D sculpting surface that runs in the browser, with no install and no plugin.

The tool palette

Add and Remove place and delete single voxels; Paint recolours without changing the shape. Box, Line and Plane are the bulk tools - drag out a volume rather than clicking cell by cell. Fill flood-fills a connected region, Select marks a region for move/copy operations, and Pick samples a colour off the model.

Face is the one worth learning first: it paints or extrudes across a whole connected surface at once, which is how you resurface a wall or a floor without touching every cell.

Voxel layers

Layers work like they do in the 2D editor. Each one holds its own voxels, edits go to the active layer, and a layer can be hidden or locked. Because the layers stay separate in the file, you can restructure a model later without having destroyed anything.

3D stamps

A stamp is a reusable chunk of voxels - a window, a wheel, a tree - saved once and placed anywhere. They sync with your account, so a stamp library built on one machine is available on the next.

Smooth surface export

The Smooth surface (rounded voxels) export option runs a surface-nets pass so the exported mesh is rounded and organic instead of blocky. It is an export-time look only - the editor itself stays cube-based, so you keep editing cells while shipping something softer.
