pixemboss vs Voxel Builder

Pixemboss is a browser-based editor for turning 2D pixel art into low-poly 3D models for games. Its 2D workspace includes shapes, layers, frames, per-pixel depth, stamps and palettes; the voxel editor adds sculpting, voxel layers, baked ambient occlusion, emissive and metallic materials, and dynamic lights. Models can be rigged and animated, with animation clips exported in GLB. The editor exports 3D formats including GLB, FBX, OBJ, DAE, STL, VOX and glTF, as well as sprite sheets, PNG, GIF and WebM. One-click import kits are available for Godot and Unity, and the Godot guide describes a plugin with a live-link workflow. Per-pixel depth ranges from 1 to 8, while unpainted pixels add no geometry. Some export details matter: cone lights and fog are viewport-only, and emissive or metallic properties reach GLB only with Palette texture colour mode active and Unlit off. Rigged exports use one plain material, so those colours appear flat. Pixemboss is free in the browser and can be started without installing anything or creating an account.

Voxel Builder is a voxel-based 3D modeling application for creating and editing voxel scenes. It includes terrain, cube, sphere and isometric generators, alongside interactive modeling, symmetric drawing and painting, transforms and color groups. Rendering tools include a Three.js sandbox, GPU path tracer, basic PBR rendering and post-process effects. The app can voxelize GLB, OBJ, STL and PLY models, as well as images and Unicode or emoji text. It saves and loads JSON and MagicaVoxel VOX files, and exports GLB, GLTF, OBJ, STL and PLY. Local storage, snapshots, quicksave, undo and redo are available, with snapshot backups shareable in ZIP archives. A Blender importer script is included, and baked GLB meshes can be used with Blender and other 3D software. The project describes the app as portable and usable online or offline, with no ads, trackers or logging; its code is GPL-3.0. Browser use is supported on desktop and mobile, and Electron downloads are listed for Linux x64 and Windows x64.
