pixemboss vs SpriteStack

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.
