Our verdict on MB-Lab

MB-Lab is an open-source Blender add-on for creating and customizing humanoid characters. It is aimed at artists, developers, and creators who want human avatar generation inside Blender rather than a broad library of avatar styles. Its workflow covers model templates, morphing, phenotype controls, measurements, skin, eyes, hair, facial rigs, expressions, poses, proxy assets, and rigged character finalization.

The feature depth is strongest around character customization. Morphing, phenotype, and measurement controls support detailed changes to a humanoid model, while skin, eye, and hair tools extend the appearance workflow. Custom facial rig and FACS rig support add control for facial performance, and expression and pose tools provide further adjustment. Proxy asset fitting is included for fitting compatible assets to the character. Finalized characters can be saved as Blender files, with character parameters preserved as JSON.

Blender compatibility is central to the product. The final release supports Blender 4.0 and later, and the published export workflow lists BLEND and JSON formats with rigged exports. However, the project was archived on July 21, 2024, and version 1.8.1 is identified as the final release; development moved to Charmorph. The generated 3D models default to AGPL 3, which may restrict use in closed-source games or closed-source 3D models. Choose MB-Lab for a free, Blender-focused humanoid workflow when its licensing and archived status fit the project. Teams needing ongoing development, support, or a broader active ecosystem should choose an alternative.
